The Hardest Carry
One of the most powerful ways to win in League of Legends is to "put the team on your back", so what if there was a champion who could do just that. A Q that rallied his teammates similar to Sivir's ult, in which they are buffed in some manner. His W can taunt, making the target champion only able to attack him, and win infinite 1v1's against them. E will be able to verbally assault the enemies and hurt both their feelings and their HP, in a cone similar to Talon's W or Cho'Gath's W. And finally, his Ult. Oh baby, his ult. A simple press of the R button puts the champ into a kneel, and allows any or all of the remaining team to teleport on his back. He can press the R button again to stop the ability and release a shockwave that knocks up enemies and puts the team in a glorious 5v1. (OP so probably needs ultra long cooldown)
I understand the champ is OP af so any nerfs that you feel are necessary are kindly accepted, we don't need a champ with a 100% win rate.
