chogath is an archaic champion and he needs some tweeks
once upon a time, there were champions that had no mobility and long cooldowns to balance their burst and tankiness or cc. pretty much all of these champions were reworked such as sion, but chogath remains. that doesn't mean chogath is poorly designed or whatever, it just means he's either going to be overtuned or undertuned at all times which is silly. Right now, getting hit by rupture after level 6 as a squishier champion is virtually synonymous with dying to chogath, which is pretty stupid imo considering how tanky and sustainy he himself is(he can wait all day for that one q to land). however, if he got nerfed to where you could survive his combo, you'd probably just be able to kill him all the time with ease. I think that to make chogath more reasonable his q OR w OR r base damages should go down and he should in return get lower cooldowns and mana costs.
Yeah i just lost to a chogath but i also exploited him a few games ago for an easy win because i only play one champ and he got banned so i needed a brainless champ to play and i also used to main him so not QQ
