I know as with many other skills, gains in esports like Overwatch increase logarithmically. Meaning progress slows overtime. Be sad.Truth is, for genetic lottery may be more deterministic of one's standing in this game than most of us would ve comfortably with. I just feel so slow and my progress will in fact only slow. Is this rank afer 200 hours with a single character as a new player normal?

I believe all 4 characters popped their ults in a similar timeframe, or potentially an echo got 2 in a single activations. This was way back when echo would clone tanks since her health didn't get reduced at all

I'd appreciate any pointers

Overview

Cosmic Coolant serves as a cooldown reduction power that scales directly with [Pulsar Torpedoes] hit count. Its strength lies in tempo control rather than burst damage. When paired correctly, it enables a reliable cast loop that supports sustained healing output.

Context

Cosmic Coolant was once the must pick for Torpedo damage focused Juno. After the nerf from 1s to 0.5s per target, it no longer qualifies as best in slot for damage.

In Season 5, Blizzard nerfed multiple AP and CDR items, making ability base spam harder to maintain. As a result, this guide focuses on a specific play style. A bulky sustain Juno that relies on tempo cycles as a hybrid healer.

Core Mechanic

Cosmic Coolant: [Pulsar Torpedoes] cooldown is reduced by 0.5s per target hit.

• Pulsar Torpedoes base cooldown is 10s.
• Each target hit 0.5s equals 5% effective CDR.
• Biotech Maximizer adds another 5% CDR per healing target hit, resulting in 1s total CDR per heal.
• This power should always be paired with [Pulsar Plus]. Do not take Cosmic Coolant without taking [Pulsar Plus].

Use Case Breakdown

Damage Focus

There are 2 ways to use Cosmic Coolant for damage:

• Sustain damage applies steady pressure against teams with limited group healing, such as Ana or Zenyatta.
• Burst damage depends on landing exactly 3 torpedoes to secure a kill. This was possible in prior seasons where it reduces by 1s per hit instead of 0.5s.

Single high damage torpedoes as a finisher or clean 2-shot kills are more effective. Sustained low impact torpedoes mainly feed enemy support ult charge, which often outweighs any gain. The goal is to win games, and kills worth much more than just spam damage. At higher levels, landing 3 torpedoes is rare outside of overtime or favorable map geometry.

Though experiment

In prior seasons. At 1s CDR per hit instead of 0.5s, 2 torpedoes hitting 2 allies and 2 enemies would grant 8s CDR, effectively you only need 20% CRD from items, allowing you build into more damage and making 3-shot possible.

To land 3 torpedoes while benefiting from Cosmic Coolant, assume one cast hits 2 allies and 2 enemies with the first 2 torpedoes. This grants 4s CDR, leaving 6s still needed. That remaining CDR is very hard to find in practice. With Biotech Maximizer, you gain 6s CDR, which still leaves 4s short. The only way to reach this ideal 3-shot setup is 51500 with 4 purple items and 2 blue CDR items, including Vanadium Injection (+10% CRD with ult available). From my Orbital Ray analysis, Juno likely not have ult for roughly the first 60% of a match, making this setup rarely achievable in meaningful play.

For this reason, I do not recommend Cosmic Coolant for damage focus builds.

Healing Focus

Healing focus is the primary and intended use for this power. While it is possible to use this power for damage. Healing focus will yield more consistent results.

• Pulsar Torpedoes ability recovery is 0.3s.
• Lock on time ranges from 0.5 to 1s.
• Targeting can take up to 4s.
• To reliably hit 3 to 4 allies, expect about 2.5s per torpedo cast.

The goal is to establish a "repeatable tempo" rather than react based casting or spamming casting.

Healing Rotation and Tempo

With no attack speed investment:

• One primary fire pop cycle is 0.77s.
• This includes 0.45s recovery and 0.32s volley fire time. If you are interested in the technical analysis, see my Juno Mediblaster Analysis.

You almost always want to take [Medicinal Missiles] to increase primary fire healing by 50%. During the 2.5s [Medical Missiles] window, you can fit 3 pops. After accounting for repositioning and human error, the target throughput is to fire 1 torpedo every 5s.

This creates a fixed loop:

• 2.5s spent aiming and firing torpedoes.
• 2.5s spent on primary fire, 3 primary fire.

To maintain this loop, you need:

• Cosmic Coolant
• Biotech Maximizer
• 20% CDR from items
• Consistent hits on 3 allies, or 2 allies + 2 enemies.

Cooldown reduction can disrupt muscle memory. In a fixed tempo loop, this setup remains stable as long as team positioning allows it.

• Avoid this setup with diver comps such as Winston, Doomfist, Tracer, Genji, Lucio, Moira... etc where consistent multi target hits are unreliable.
• Prime teammates are Zarya, Reinhardt, Torjorn, Ashe, Cass, S76, Brig, Kiriko where you can take full advantage with Cosmic Coolant

Why [Pulsar Plus] Matters

With 20% CDR, torpedoes drop to an 8s cooldown. Cosmic Coolant and Biotech Maximizer reduce this by a flat 3s, resulting in an effective 5s recharge per charge.

Without a second charge, you would need roughly 45% CDR to force recharge inside the cast gap. With 2 charges, you only need to match the average output of 1 charge every 5s.

Special Interaction

Kiriko [Clone Conjuration] adds value. If Kiriko uses clone TP for healing uptime, the clone counts as an extra target. Since Kiriko must TP into an ally, this provides a reliable additional hit.

Item guides

Earliest possible setup by round 3 taking Cosmic Coolant as 2nd power needs 28000 cash:

• $10000 Biotech Maximizer (~15% CDR). Required.
• $4000 Kitsune Snippet. Overhealth gadget, 5% CDR.
• $4500 Multi-tool. 10AP, 5% CDR.
• $4000 Ironclad Exhaust Ports (IEP). Overhealth, 10HP, 5% CDR.
• $5500 Icy Coolant. 10WP, 5% CDR.

Optional items if you have more cash. Listed by swap priority.

• $10000 Martian Mender (MM). Swap in for Ironclad Exhaust Ports or Kitsune Snippet for steady self healing. 3% self heal, 5% CDR.
• $11000 Hardlight Accelerator. Swap in for Icy Coolant if you want more weapon power. ~20WP, 10% CDR. It has great synergy with Juno having 3 ability casts + gadget. And helps with tempo primary fire weaving.
• $12000 Iridescent Iris. Swap in for Multi-tool for more AP. 15AP, 10% CDR. Poor value for the cost, only worth considering as a 6th item.

A bulk tempo build where enemy will have hard time killing you while you keep your team hard to kill. Drawbacks is relatively low damage output in a Torpedo focus build.

• $10000 Biotech Maximizer (~15% CDR). Required.
• $11000 Hardlight Accelerator (10% CDR). Improves primary fire healing.
• $10000 Martian Mender (MM) (5% CDR). Steady self healing.
• $11000 Lumerico Fusion Drive (LFD). No CDR but with this item and Martian Mender, you are very hard to kill, allowing you to maintain tempo without trying to avoid damage.
• Choice of damage item. I recommend Pulstar Destroyer. The single item that grants the most ability damage. Equivalent to 42% AP. Alternatively, Superflexor maximizes overall tempo output.
• Choice of 5% CDR item. Ironclad Exhaust Ports is cheapest solid option.

You will sit around 500 HP with this build with HPS value following tempo. In the tempo, 50% healing from Medial Missiles is always active for primary fire. Torpedoes healing: 256 / 5s ~= 52 HPS per target, so hitting 3 targets gives 156 HPS. Primary fire healing: 82.76 x 1.20WP x 1.5 (Medicinal Missiles) ~= 149 HPS. Self sustain: 500HP x 3% (MM) + 50/3s (LFD) + 25/3s (IEP) ~= 50 HPS.

Conclusion

After the nerf to 0.5s per hit, Cosmic Coolant becomes a tempo based power that rewards structured healing rotations. Its strength comes from predictable cooldown loops, not reactive burst. When paired with [Pulsar Plus], Biotech Maximizer, and a stable team formation, it enables sustained healing throughput with minimal downtime. Outside of these conditions, its value drops sharply.

IGN: Sushiii

Both games are only Illari. I've been stuck in high plat support for a few months now, with little to no improvement. I've reached Diamond once (a few days ago) but went back to Platinum very quickly. I don't understand what's going wrong and would like someone else to tell me. (In the Blizzard World game, you will see 1 or 2 times where I accidently use my Outburst instead of Pylon, I have my abilities set to my mouse buttons and occasionally press the wrong one)

If you need more codes, I can give them.

Description of the match / things you want reviewed: This is one of the worst map for Moira, however, I feel I did good in the match until last point.

I feel like I was too rigid to heal my 20 death McCree and abandoned Winston who is constantly diving alone (Even though there is no one speaking in VC but I should still spot Winston and dive with him then we won already).

I feel like my ULT usage is also terrible.

Please help me to win this match by giving me some advice.

My thought is if I just let that McCree die and focus on helping Winston to dive, we could’ve won already.

Thank you!
