That fact that it's POSSIBLE in his current gear isn't relevant. He's failing. If you're succeeding, it's probably because you have more effective DPS or Healers or a better group composition which compensates for what is honestly a slightly undergeared Tank. The OP clearly doesn't have that luxury, and in lieu of finding a different group to run with, he needs to gear up somewhat before he progresses further. I fail to see the "stupid" here.
