How to Fix Rengar.

Remove bullshit AoE Q, make it how it was before it's just clunky as all hell right now.

Remove W healing so it's actually not aids and doesn't force him into a bruiser off tank playstyle. Make W do X Bonus damage to monsters and heal him for that so he's actually encouraged to use it for sustain. He should be able to one shot shit and CC should be his counterplay.

Instead of forcing Rengar to position awkwardly to use his ult on who he wants, make his E do no initial damage but cause his next attack against an E'd target to deal bonus damage or crit. This would encourage skill in Rengar's kit as he wont get his full combo off if he doesnt properly E you while jumping, similar to how Camille's W + E combo works. This would also allow people to bodyblock the adc instead of just cockblocking rengar by having an orgy with them.
