As my opinion, these weapons are still OP.
The Lavaspray is still OP with this "Max Heat Damage" and "Cooldown Damage".
The same with the Coldfire: Its Overpowered by the "Max Energy Damage" and the "Regeneration Damage".
I think the "Max [Amount] Damage" and the "Regeneration/Cooldown Damage" should be removed on this Weapons.

The Cooldown Blockers are OP too.
Reasons:
-It has the SAME weight (!!!) as a Needle Blaster II.
-Already 2 Cooldown Blockers and some Flamethrowers can convert a simple fight into a long, boring and nonsense overheating story.

SOLUTIONS:
-Change the weight to ~80kg.
-When Cooldown Blockers drain Cooldownpoints, other equiped heat weapons should heat less.
EXAMPLE: Cooldown Blocker Drains 20% of Cooldownpoints, the other weapons should heat 20% less.
Please change the stats of Cooldown Blocker Mk I before launching the Mk I.

I think it would be great if these changes could be included in the next Weapon Balance Update.

you have some good points but I think this still needs tweaking.

Lava spray needs to be reduced to range 1. Coldfire with range 1-2 is understandable. HOWEVER, with heat weapons, you can overheat and you have no chance to get away. They need to stop releasing weapons without testing them. *cough* Alex, Liran take note.

On a note with testing, If you guys do want a team of testers with gameplay experience, I'm up for the idea. (I'm really getting sick of new mythicals just popping up without a thought.)

I gladly approve your point there,hope they will indroduce a testing team because no one uses the dev servers anymore but myself a few devs but that's it

A testing team is seriously needed since a few items are complete "trash" in the Mythical Section. One example is Red Rain being a tad bit better than Heat Orb for 15 rockets and more weight. That 65 rocket module is costing you valuable health or energy/heat modules, making Red Rain pretty useless. Don't even get me started on Metrolens now, that thing needs a buff. I completely agree with the testing team idea, you can't make a game without knowing what you're making.

100% agreed with everything here.

Metrolens... HHHOOOOMMMMMYYYYGGAAAWWWWDDDD (triggered) seriously a useless item ever since it's release. Id rather have any Galaxsus Model, and I do. I also have two Metrolens

See the thing is, the developer isn't considering the effects that the release a new item(s) might have on the rest of the item populous. Example, Rear Hit Marks. Instead of making them worse, the developer simply made orb cannons better. This in turn now made Red Rain, BackStabbers 1-2, and Wipeouts 1-3 pretty much useless. Honestly when was the last time you saw any of those used by a top player? lol.
