Well, I did AK once with a fresh 50 Pld who had all his gear broken (insert /facepalm) and I was using my i90 Monk atm, since he had less hp than I and less....well everything, I tanked the second half of the dungeon run (before Demon Wall all the way to the end) without losing hate to the healer and not dying at all (pro healer FTW!) Just using FoE and the defensive cool downs that I had on hand, while it's not at all optimal, I'd say that even as a Monk you could do this.
