MSTRIKE UAC or a waste of points?

[CaptContagious]

I was liking MSTRIKE with UAC but after a few arena runs it seemed much quicker to just use aim strikes. Is it worth it later on?

[Ososis]

I am not UAC, but for my arena runs it all depends on the critter.

Tsarks and Grhanks get head ambushed, regardless of stance
Servants, witches and other muagicy turtle bastards get feinted then ambushed
Burgee's, basalisks, yeti's, mammoth's and champions get MSTRIKE or berserked,

It's way quicker to do an aimed shot, but sometimes you just need to deliver massive damage.
