Can we do something about insane amounts of heals in this game already? Looking at Sylas and Kayn..

Can't build enough to deal with these two champs

It's not a big deal when it's gradual on champs like adcs, even though crit is a bit busted atm.. But when you almost kill Sylas and Kayn, and they just heal back 60% of their fucking hp bar by simply looking at you, it's a bit ridiculous already Riot.

Why do these champs even need this much healing to begin with?.. Especially Sylas. Even an incredibly bad Sylas can do terribly in a fight, and still win a trade.. or frontline.. or kill an enemy champion simply because he outheals them, and for no other fucking reason at all. How is this actually a thing??

And is it not bad enough that you can't catch Kayn, fucking. ever. He needs to heal back everything and tank 1v5s just by existing?

Nerf it already, for god's sake. Or better yet, remove it.. why does every new champ need assloads of healing, shields, or insane safety of some kind, with an already overloaded kit? What ever happened to counterplay in League of Legends.
