Why people says AST is bad?

Fey Wind got buffed. It used to increase skill speed and spell speed, and they were on seperate timers. The only time those were better than the new Fey Wind is if you actually had enough spell/skill speed so the multiplier was worth it.

Fey Wind used to be two parts that gives 30% skill speed or spell speed. Now it's both speeds at a tenth of what it used to do. It's a nerf.
