I'm perfectly ok with the Cho R buffs, but FIX HIS W
Currently Cho'Gath's W checks for hitboxes at the beginning of the cast, giving you the illusion you can escape it while you actually can't, which leads to burnt flashes just to die .75 seconds later, etc. FIX, not nerf, FIX that and most of the insatisfaction to play against him will disappear. Then, if that hidden power was too big of a part of his power, just make Q's hitbox larger (currently, so many times it should hit and it doesn't) and move part of its casting time into delay where Cho can walk around. This allows him to kite better and have a better fallback pattern.
is a champion who is thematically great but just needs to have his kit updated. Currently his kit is more terrifying than Cho himself is ( and Cho is the Terror of the Void ) and there would be no need to delete him if it were fixed in a way O.P. suggested.
