Zac would need nerfs mark my words!
Zac is too dominant atm and he would need nerfs
Maybe not in the next patch but i am sure as he get more and more dominant in games he would get nerfed!!!
And that is happening because is the only tank that have some CC and he can survive the shit load of damage the game have atm and he can do stuff in team fights
But he is WAY too dominant atm

. He doesn't even do much damage, just ignore him and get to the backline or focus him first to kill him faster. Also most of his moves cost health, so he's basically killing himself by attacking you with skills.
