I think Xerath needs a buff
I don't see him very often and I've just recently started playing him. I originally thought he was op because of that poke... Honestly, if he's going to hinder his OWN MOVEMENT SPEED, and which he already has no mobility to begin with, he should have higher damage than what he has...
Just me?
Oh and his ultimate doesn't feel like I'm unleashing the power of a near god-like entity. Maybe re-add built-in penetration. He is a poke mage after all.
