there is no need to ever use Cooldown unless you are already overheating, which feels all sorts of wrong.

There is need to use Cooldown when you want to keep attacking while you know the boss is about to change phase to don't overheat while the boss is invincible or untargetable. There is nothing wrong, and it feels like you didn't play it to believe we just straightly use Wildfire 100% of the time we can like if you never faced a monster about to die or a boss about to change phases, so you still want to attack but delay the start of overheat thanks to Cooldown. (I didn't say you don't play it, I really mean it feels like you forgot that part of the gameplay like if you didn't play it to never faced it).
