Well, what if they implemented something like every champ with a spamable ult (lets say <10 sec cd) gets an increased cd on it globally?
This would make kassadin at least a little easier to deal with
Swain would be hurt, but I think skillful play could make up for this. Same for anivia
if the increased cd was % based, kog wouldnt be hurt much. same for akali, teemo, corki, Darius, Diana, Irelia, khazix and karma.
xerath would be slightly hurt by this, perhaps make him immune to it.
jayce would be toned down some, which people would like. nid and elise would suffer this nerf tho.
So there would be a few nerfs accross the board, but some OP champs would be toned down. What do people and Riotnome think of something like this?
