if riot would remove someone or a group of champ who do you think it would be
he is so hard so balance you seen how
turn his op mode on and nurfing it hard him allot
they have so much pact in his ult that they can never let him stay good for long and they need to gut him in other ways
it's like he was made for a dif game not league
this was the champ that got them fighting and they openly told us they wanted to remove
\ ps on your list this isn't whing that a champ is op plz state fact not just they are doing good right now like they say
it the best assassin with the most coutner play at one point
something like that they all have things in their kit that are unhealthy in riot's perspective
The troll with the troll pole that's allowed freedom to troll 
- Kill off the double crit chance, kill off the 50% bonus armor pen for 15 seconds on ult - buff the shield and his ult damage, but put Q and E on higher cooldowns (removing the E 10 second restriction since it'll be about three seconds even with cooldown) and you have an actual champion who isn't massively powerful to the point of destroying everybody with one single item.
Nerf the amount of her E, take out the W stun because she already has a brief stun/knock-up effect on the Q, and reduce her passive damage. She'll still be super strong.
- No more critical strike chance, no more true damage. Make him a tank, and stop giving him more damage than half the ADC's in the game.
