Ahri E Bug
Several patches ago, a "bug" in Ahri's E was fixed so it no longer stopped jumps. Obviously this was a nerf to Ahri, but I understand wanting clarity and the removal of outliers.
However, Ahri has a different bug that effects her E that is still in place, and only applies in edge cases uses, and it seems important to remove it as well. If a Ahri dies while a target is taunted, the taunt ends. Sometimes this does not matter, however I have faced many a tower dive where, had this bug not existed, a 1-1 would have occurred, and it is extremely frustrating to experience and it is especially egregious when there exists Thresh, who can die while Q'ing someone and the Q's duration persists after death even though that makes less sense than Ahri's case since he's Q is literally pulling someone towards him rather than charming them to fall in love.
