- Change Cooldown to be an oGCD ability instead of a weaponskill. Reduce potency to compensate. Maybe make it only work when above 50 heat.
- Change the 1-2-3 to gain more heat per activation (like 15 or something), to align with the change to Cooldown. Don't change the heat gained with ammo usage.
- Make Flamethrower quicker, or something like allowing me to move while casting it. This would make it a choice between getting to 50 heat for single target or AoE situations. You wouldn't need to double-use them since it'd be fairly quick to get to 100 heat.

This way, MCH gets what it should have had: 1 mechanic acting as 2 mechanics. You Overheat when you want to Wildfire, and you manage heat while WF is on cooldown.
