Mikael's Crucible buff

What if it cleansed literally everything, save for displacements? Zed/Fizz ults and the like too? QSS used to be like that, but before you call it BS OP hear me out.

QSS indeed was stupidly OP on its own because it was the target that was buying and using it. But if it's the support instead it will make it trickier to use in bigger fights. Lowering the cast range to 450 units or so and prolonging the cooldown can help balance its effects out. ADCs and Mages are still going to be vulnerable when alone, but a good Support is actually going to be much more impactful. Hell, it may even encourage teamplay.
