Except... You're not gonna build up enough Ki on Gromp. A full rotation is going to give you like 20-25 Ki. The whole idea is that you're not going to build up enough Ki without fighting champions.

And on top of that I'm not convinced Riven can survive the new jungle early. Would have to try that out, but she always took quite a bit of damage the first few levels.
