Rengar needs buffs

Make his passive jump give him a 2 second fear in a small AoE Q needs to have AD scaling increased by 50%, and should heal him for 10% of the damage dealt. Cooldown needs to be lowered to scale with AD, capping out at 1 second when he gets 200 bonus AD. W should give him 30% damage reduction instead of some measly armor and MR. 50% for empowered. Also make it scale of off 50% bonus AD so it actually does something instead of just being a useless ferocity generator. Also, he should generate more ferocity for every champion hit after the first. E should lock on to targets again and should also have AD scaling increased by 10%. Enemies hit by empowered E should also take 20% more damage R cooldown needs to be lowered and he should be able to reactivate it for a second, shorter burst of invisibility like Kha. He should also gain the 5 ferocity instantly, the moment he uses his first wave of ferocity.

Otherwise, he could use some buffs to his base AD and HP

Maybe with these changes, Rengar will finally stop being a troll pick and see some play outside of beginner bots
