Since your balance designers are obviously incompetent, here is how you rework rengar:
q-> Rengar doesn't need a dash on his q. Get rid of that, keep everything else the same.
w-> Replace grey health, cleanse and cc immunity with: "Battle roar grants rengar one stack of ferocity for each enemy damaged. Battle roar is refreshed on a kill or assist"
e-> Same as now plus can be used while stealthed, while empowered if it reaches max range the bola falls on the ground; rengar can jump to the bola while it lasts (cat toy). Disappears after 3.5 seconds.
r-> as it is currently
Now rengar can choose between being able to cc the target / do heavy damage to the target / set up a cat toy as a safety-net backup plan.
Not this retarded shit where he does damage, cleanses and olaf ults away while being tanky as all hell through grey health instant regen.
