Don't see why not.

Silence, intimidating shout, revenge stun, concussion blow, spell reflect, hamstring, intercept, intervene and the lol there's a warrior with a shield in here factor.

Just before i crit for 2k on cloth with my shield slam.

Too bad i don't pvp much these days

I was just trying to show that prot warriors are viable for pvp... not imba - just viable.

And power word shield has a 50% chance to be dispelled by shield slam, after which it hits for full damage. For only 17 rage which is not that difficult to get. With focused rage, a prot warrior has a lot of cheap attacks which can disrupt the opposing teams healing. And that's the person i'm going for at the start - the healers.
