Her ult is a terrible mechanic that doesn't belong in the game as it it now.
Lmao, and Fizz's troll pole does?
Vayne having counterplay removed does?
Her ult actually requires proper timing in order to make the most of it. It isn´t just hurr durr press R at any time and survive everything, like Tryndamere's ult is, which, by the way, is a little over double the duration of Kayle's ult.
She's nothing but point-and-click
EVERY CHAMPION IS POINT-AND-CLICK. She has TARGETED abilities. There is a very clear difference between point-and-click and targeted. The former involves well, everything in a match of League. Ward placement is point and click, skillshot casting is point and click. Even editing configs is point and click.
So boring as fuck to play and to play against
I find Kayle fun to play. Fun is quite a subjective term. As for playing against her well, you got Irelia, you got Quinn, you got Pantheon, and if played right, you have Riven.
She isn´t receiving a VGU for quite a while, as there are quite the amount of champions ahead of her. And as Riot stated, they won´t update her without doing stuff to Morgana, since their lore is basically the same, but from different perspectives and with different outcomes. If it happens next year, it will most likely be near the end of the year.
