So about Cho'Gath's ult and Sion's W
I love the entire Cho'Gath buff, but the thing is... He does what Sion does faster and better. Now before anyone butthurt over this says that Cho has a stack limit at 255 and Sion can go on forever, you have to take in account that none of these are realistic.
Now what is realistic is Cho having 10+ stacks late game and rocking around with an extra 1k~2k health just sitting there while usually building full AP and ol' boy
has to farm all game and maybe throw in two or three HP items in order to get that kind of love.
I just don't think it's fair for Sion's whole infinite HP gimmick to be stolen so quickly by our lovable void spider-monster-thing Of course, that's just me being biased because Sion's one of my mains.
