Watching BeyondTheRift was funny and insightful
Scarra, "I looked at my win rate after two weeks and I had 20% win rate with this champ over fifteen games"
Yoona, "that champ is so fucking worthless"
scarra laughs
Yoona, "who cares if like he can eat an infinite amount of things he still.. Fucking.. Sucks."
Imaqtpie, "yea youre like
teed to lose lane with him."

What if as he increases in stacks, his Q gets very slightly bigger each time? Or... Well something, because what happened to chogath was hardly a buff because post five stacks it's nearly impossible to get an execute on a team with half a brain. You basically have to pray that you can chomp the enemy tank, or every 6 minutes I guess you can try to flash r the enemy carry if theyre low enough...
With the amount of HP per stack lowered, maybe you can try making it so that after five stacks, ults on champs grant double stacks? Or perhaps have milestones? At 5 stacks you gain permanent 2% bonus hp modifier. At 10 stacks, you gain a permanent 5% bonus hp modifier, at 15 stacks (if you somehow ever manage to get there...) a 10% bonus hp modifier, etc. SOMETHING.
It is worth noting that according to http://www.op.gg/champion/chogath/statistics/jungle chogath, in all three of his prominent roles, saw no significant change in his horrible ass win rate after the changes. The changes gave him an awesome dream that realistic players know they can never achieve.
