We need more "mind control" abilities in the game
There was one time I thought "you know what would be cool? If there are champions that can destroy enemy teams by using their own carries against themselves.
Like Mordekaiser's ultimate, except not just limited on one champion.
A 2-second "mind control" ability on one champion wouldn't be too bad. It's like a 2-second stun, except better. You "mind control" their fed Vayne and you laugh while they die from their own fed carry.
It may be the best counter to hypercarries and absolutely wrecks "4 protect 1" teams.
