Wait... since when was Pacification weak? Does anyone here actually know how it works?

First up, Pacification has a 6 second timer by default. That's far longer than most enemy skill times. Secondly, while it doesn't interrupt them, it DOES prevent the skill from firing at the end of the cast so it still saves you from needing to dodge an attack. Sure, over time the pacification time will decrease, but that just means it's up to you to time your skills better.

I personally use it all the time. In parties, on bosses, in Fates. Anyone who thinks it's a useless skill really needs to take a second glance.
