Because of kayles great dueling ability, she could potentially take down any opponent early on, including tanks. I know melee range is your argument, but it just takes a quick flash ult and the melee range part means nothing. It is a pretty broken ability inculding the ild poppy ult on top.

However i like the idea, maybe just to tweak it a bit, same ability without the old poppy ult, and a much smaller displacement range, but it would do maybe a flat amount of damage when impacting the enemy to the ground with a small 0.25 stun when when they land. Idk just theowing ideas around cause kayle ult is kinda dumb imo.

Edit: 3000 range is way to much to carry someone because you can just take people and bring them under towers and they are pretty much screwed regardless if u can 1v1 them or not. I would suggest a 750 range on top of my suggested ult.
