How to fix Rengar.

As some of you may have recently realized, Rengar is once again broken, (this time as a bruiser/tank top, that can jump on his enemy, deal a bunch of damage, take just as much damage, but then press W to heal most of it, and W again to gain CC immunity and get out.)

I'm proposing these changes, to fix Rengar (nerf him as a bruiser/tank/sustain top laner and revert him into an assassin)

First of all, Rengar W needs to be gutted (remove or nerf the insane heal, and nerf the cc immunity), and nerf/revert his passive, maybe even a damage nerf (on Q, or crit from ult) in exchange, PLEASE revert the ult indicator so we can actually be an assassin again, and hunt people in the mid/lane again. Right now, Rengar sucks when played as an assassin and not a bruiser/tank. his ult is basically a scouting/zoning tool, rather than a hunting tool. you still use it to get in team fights, but apart from that, unless the enemy is stupid enough to not run/group when they get the ult warning and see u coming from miles away, you aren't hunting anything.
