When you're the primary target of a creature version of Int shout I believe it stuns you, unlike the player version. If you're tank is running around after an Int shout, he wasn't the primary target and didn't get stunned.

I haven't tried this personally, but I believe the creature version of Int shout that stuns you and makes the mob turn away to bash on the other members of the group is NOT removable by dispel. Hell, I just started playing a paladin myself and haven't had a chance to try it, or even to try and dispel normal fear, but i'm 90% sure that a normal fear effect is dispellabe.

This new change is freaking awsome for anyone that had problems with those fights ziran highlighted. I'm one of the ones that couldn't stand SP trash for this reason. Granted I've learned to deal with it after a few runs, but when I first encountered it it was really difficult.
