Cho'Gath mini update was pretty lazy
Dont get me wrong, I love how they are finally giving attention to some older out of spotlight champs without having them go through a full VGU.
But by changing Cho'Gath but not looking at how most things effect him, the balance team just put a lazy band aid on him. Because atm Cho can grow so large that Sunfire and cinderhulk no longer deal any damage because they do not extend outside of his ulti. His Vorpal Spikes hitbox grow as Cho grows, but his W doesnt. So you have a huge cho with the same scream as a level 1 cho.
IMO, Cho should be all about size. His Vorpal spikes should grow, his W size should grow, hell, maybe even his Q should grow if Cho gets big enough. They could make this his passive, and the bigger cho gets (to include things like
ult, etc.) the more impact his abilities have.
