Camped this mob for a while last night. I was fortunate to default win this item (real winner was already wearing one.)
Now, I'm not the best geared tank (8500 hp, 1670 ac) but I do have all the Defensive AAs through PoP Adv and they prove to be of significant value in MPG. Also of real utility is a cleric with Pious Elixir HoT and a self-healing tank such as I am.
I died only twice in about 4 hours of camp and I was the only member to die, which is good from my perspective as their was little downtime and no wipes. In fact, both deaths were the variety of the mob being below 15% health and NOT running. I don't know if this has been discussed elsewhere but what I found is that a number of mobs in MPG do not run when at low health and continue to mete significant damage up to expiration. I think this is an outstanding zone and I am looking forward to more of it.
