I can't check your armory because it's currently down for maintenance, but I'll have no problems tanking 10 ToGC as a warrior - though I suppose my guild probably out gears the encounter now a days. The strat we've always used is I'll take 4 stacks of the impale, getting BoP'ed on the 4th, the other tank (a paladin) will then take him, bubbling on his 4th stack, then we just split the remaining stacks between us. If you're dying on only the 2nd stack, that may be an issue with your healers.
