Sup folks and good day to you all in Eorzea!

I have been leveling my Warrior to 50 and never notice pacification much until the later dungeons and beginning end game content. It seems to constantly pop on me. My questions are:

1 - What cause Pacification? Myself or mobs?
2 - Is there a way to minimize Pacification from occurring so much?
3 - Why does it seem that I am the only lvl50 WHM that removes this buff?

Any help would be greatly appreciated, as I would love to offer better tanking skills to the limited pool of Eorzean tanks!
