Why does Yorick have a 140s cooldown on his ult at level 16?
Basically, Yorick is a huge outlier in how little his ult's cooldown scales down by rank.
Currently, his ult cooldown is 160/150/140.
The only champs who have a higher cooldown at level 16 are
(200/180/160) and
(same as karthus now, but it was 180/160/120 before 7.8)
Yorick is tied with
at level 16 (gangplank's ult goes 180/160/140)
Every other ultimate in league has a lower cooldown. Most fighters have an ult that scales down to about 70-90 seconds, but for some reason riot thinks that Yorick's ult deserves a cooldown as long as a global ultimate.
I think riot is under the impression that the best use of Yorick's ultimate in the late game is to send the maiden to splitpush a lane (which would make his ult "global").
However, Yorick can't afford to send her to split because he needs her more than ever in the late game. The maiden gives yorick the damage he needs to duel AND is the only way for yorick to summon mist walkers for teamfights.
I would love to see the cooldown reduced or at least start on cast like
ult and make the maiden last for 60 seconds. However I doubt riot will make any changes because Yorick seems to be once again forgotten.
