Cho'gath has serious balance issues.
Hi. Id like to say ChoGaths kit is more BS than Irelia's kit.
First of we have AoE Knock up with high base dmg, then we have AoE Cone Silience with high base dmg which is kinda unfair and hard to dodge! as the third main spell we have an On hit Long range poke ability which deals magic damage. Then we have an ult which deals True damage and has an execute indicator which gives stacks which grant Health. really?
You really have to tone down his kit! Silience is way too long and his bases are pretty high too. Is he a mage or a tank? It seems like its both with full ap build. And something called its passive gives him no weakness. His sustain is awefull but you get rewarded for playing the game properly, farming. I mean really? you dont have to try and you regen 20% of health with a few minions.
Do something about it, he is dominating the toplane right now with "toxic" gameplay elements.
-level as far as mana problems go.
