The point of this skill is to increase proc chance, which increases speed and reliability. Other than that it's pretty useless aside from tapping. Stacking this card means you'll have one less buffer,aoe, or whatever you have on your team, which means less number of procs. Sure you'll get your procs even faster but that means 1 AW field and you're screwed as you'll have less buffs to work with.

Stacking it with GUR Drum Major wouldn't work well if the lack of buffs anyway, and she's just 2 proc.
