This happens all the time, but this one really made me laugh. Using my full Dread Guard Assasin tank with the Warstalker title. Right at the start of the FP a DPS in Columi and the healer both pop out "grd plz". Good thing people try and keep the flashpoints entertaining.
I got that from a healer a few days ago. He was insisting I needed to guard him and going on about it the whole time. The funniest part was at the beginning, however. He insisted that there are no CC's to be usen in The Esseles FP as a shadow tank. You talk dumb stuff like that, you're getting guarded only after you exit the instance.
