Can we change/give an actual cd for Kayle's ult?

I'm perfectly fine with how strong she is with Sated. She blows hard early game and stomps as a hyper carry late game, but that ultimate of hers being up so much is grossly overpowered for her to be a hyper carry.

You might as well give Vayne a tryndamere ult on hers if this is how crap's gonna be.

Hyper carries SHOULD NOT be unable to die/take damage/targeted I honestly don't know why Riot keeps doing stupid crap like that.

Master Yi/Tryndamere/Kayle/Pre-rework Fiora. All of them had/have the ability to completely stomp and carry a team simply by being so oppressive. The counterplay behind that was they sucked early and were good late, except unlike someone like Vayne where you can just get a pink ward and prevent her stealth or her being super squishy these guys could all prevent you (with legit 0 counterplay) from stopping them.

It doesn't help the fact they ALL have 4 have/had in built heals making it even harder to stop their early game, but it just makes it even harder to kill them when they heal up the damage after being unkillable.

Someone needs to balance this stupidity. I don't think she needs a nerf in the damage department but she sure as hell needs a nerf on that retarded ult
