Cho'gath should be reworked (Broken but not OP)
His passive makes it near impossible to poke him down or trade with him effectively
His knockup has a slow after it so if you manage to get hit by hit he can chain the rest of his abilties
His silence is undodgeable nor unflashable. If you're in the hitbox when he cast it you're going to get silenced. Meaning if it hit's you will be knocked up.
His ult is a true damage nuke while also making cho extremely tanky because he gains more than 600 hp from it. Cannot be dodged. If you get hit by his silence/knockup the rest is undodgeable and you will die or be near death
This sounds super OP but he's not, he just has a broken kit. He can be kited since he has short range, his kit is made to deal with being poked down and catch up with the ranged champion but this created a situation where he totally shits on every melee champ. There is nothing you can do if you're a certain champion that cho counters. Again, I'm aware that cho has counterplay but his kit design leaves very tiny windows to counterplay if you're a champion who has enough ranged abilities and power to go through his sustain. If you're a melee champ you may as well go afk because you won't be able to deal with him.
