The most unfun mechanic in the game

Let's be honest, it can be frustrating to play against a fed Rengar and be oneshotted without much to do against it. But that is not my problem. In fact, I appreciate the assassins gaining a little bit of relevance again.

My problem, and the most unfun mechanic in LoL is: Gragas' E, the dash.

It is ridicously overpowered in the sence, that it got priority over EVERYTHING. No matter what you do, the dash will cancel it, unless you are immune to CC all together.

It is so extremly annoying that he can cancel your auto attacks, any spells and everything else. You are just rendered useless for an extended period of time and you got 0 controll over your champion. I am fine with him having a knockup/knockback on his dash. But seriously, if we got things like Pantheon W (stun)... let him at least be stunned too if he dashes right into it. Istead of canceling the ability and starting it's cooldown. And don't let him interrupt autohits that are way over the point of animation where you, the player, could effectively cancel it. No Gragas is not overpowered or seeing too much play in high elos. That is not the point: I feel like banning Gragas everywhere because if he is picked he sucks out the fun of the game like a vampire blood from a virgin.

I say: Nerf his E. Either remove the knockback all together or at least don't let this thing overwrite everything else.

Sincerely, an annoyed player
