Cho'Gath has insanely high base damage to the point where a full combo can literally one shot someone at higher levels even though he builds solely tank and no AP whatsoever. I hope that Riot can rework him to be a more dynamic champion so Cho can truely shine in many ways besides a giant tank that deals ridiculous amounts of damage.

or something but that's still a lot of dmg for someone that's so hard to kill
Starcraft243ver1 votesHe's slow. Kittable. Just never be in range.
KuroCaliber1 votesHe's basically the Juggernaut of tanks, he only hurts if he gets closer
J Eevo1 votesHis niche is clear, he deals a lot of damage if he lands his Q, which while great if he does, leaves him in a very bad spot if he doesn't. It doesn't come from nothing, high damage is counterbalanced by how easy it is to avoid the damage.
Now you could of course argue that the disparity between his damage and how reliable it is might be balanced wrongly, but considering his winrate statistically is very low it doesn't seem the case.
