Ahri's charm.
REMOVE IT! She has q strong movement speed boost which takes 0 skill to proc, 3 dash bs ult, fast ms due to luden's echo 10% ms core item. She doesn't need one of the best cc abilities in the game.
If you guys think that's too radical (even though it isn't), then remove the q ms boost, increase her ult cd, remove her heal passive. Such a safe bs strong mobility and dmg champ. No weak phase either.
all crying in the distance
