Rumbles overheat mechanic

I would prefer if his Q yellow zone did less damage, for it to be permanently on when he is overheated.

As of right now he's pretty damn toxic in both mid and top (level 5, rank 3 Q and rank 2 shield is unstoppable on top of corrupting pot) I skip E for more shield and damage for crazier all-ins, there's literally no reason for me to overheat when I can juggle it between Q-W on top of buying cooldown to constantly Q W. (Flamethrower and Shielding)

At the same time, if his shield and flamethrower were instantaneously popped when he goes overheat, it would make him an overall much more smooth champion without being extremely toxic in the early game.

(You literally can't do anything against him 1v1, and he has a ton of potential to kill your jungler)
