As a Rengar main...
I can honestly say I feel happy with the rework! It feels like it'll take a little learning, but will be very fun and satisfying afterwards. From what I've seen, it'll be more consistent with power. I can't wait!
Edit: It seems that everything is about cycling abilities in one fight and buying flat ad with some tankiness. A lost more AoE mid-jump comboes... More strange comboes, weaker early-game, I can't play him top anymore
THe movespeed doesn't make up for lost EMP abilities...
