Rengar passive.
Why dont you make it go up to 10 and make it have to kill 5individual champs twice? Let's say you get 5stacks and when you get 5 stacks the passive unlocks again and you can those 5 targets again for bonus ad This way the dmg bonuses wont be so high and they will take more work to be achieved. ANd the last 2 thropies should reward with more ad than the current last one cause i mean come on it's 10kills.... and his passive overall will be weaker early mid game. also nerf his W it is pure cancer and this is coming from an ex rengar main. I dont want him to get gutted for no apparent reason when you can do a change like this one im suggesting.
