new rengar is fucking busted

that new heal on w is completely busted if you ask me. especially now that rengar doesn't need to hit anything for his abilities to grant a charge.
i healed 12k damage dealt to me, well over 5 times what anyone else healed themselves for.
why did this get out of pbe

and
we're released with out any changes to balanced them when PBE boards complained about their kits?
