Mitigation variants between tank classes?Follow

Hello all,

I just started a Zerker to trio with some friends of mine. I love the class but I have a question about Mitigation. I've been lucky enough not to be the main tank a couple of times. I haven't grouped with a guardian yet, but I've grouped with a couple of pallys. I noticed the Pallys' Mitgation was near 100 for both players. I can't seem to get mine above 47. Is this one of the class differences, or am I missing something? I've completed all 6 armor quests. Other then this, I love the class. Zerkers have far more hate generating skills then I imagined. Good tanks, but maybe they take alot of damage? I don't have a control for his experiment. Please help me out with some info.

Thanks

PS: wearing a shield does absolutely nothing for me accept allow me to shield bash and lower my dps.

hmm seems a bit odd.. but I would have to say that it is a combo of buffs and equipment.. if they went for more ac based items then it would go up a bit.. and if they are migrating 100 percent all the time.. there is an issue...
