Can we have a compromise? Remove the crash but reduce the overall effectiveness of the power so 2 stacks of Rage is equivalent to maybe 1.5 or 1.25? And don't let it stack past 2?
Super Strength's damage output is garbage compared to other sets, particularly Titan Weapons, but those other sets don't have Rage. That's why I don't like the crash, because I get 50 seconds or so of good damage on a Tanker and then I get 10 seconds of zero appreciable damage, followed by average damage at best with one stack. I can mitigate the other parts of the crash, but the -999% damage feels awful. It might match the whole "Hulk turning back into Banner" theme, but I'm sure far more characters are themed after Superman, or some other Super Strength character who isn't cyclically losing all their powers.
Honestly, if I could turn Rage into a toggle or avoid taking it altogether (without reducing my "superhuman strength" to "gently shoving things with a feather pillow") I would. And I really don't like this idea that the only option for avoiding the crash is to micro-manage the power because I made my global recharge too high. I didn't do it to stack Rage, I did it to make better use of my two best powers, Knockout Blow and Foot Stomp.
