How geared are you as a tank? If you're less geared than the +1s, ask them to tone it down a bit. Worst scenario is they leave, and you get new DPS quickly.

If you ask them to tone it back and they don't (esp if they like AoE spam), let them die, and tell them that unless they focus-fire or tone it down you won't grab aggro back, and hope the heal is on your side. Its cruel...but really geared DPS that just go full-out with BFB/Raging Strikes and expect every tank to be as geared as them and hold aggro 100% of the time (even on non-target mobs) are not good DPS.

If I see this as a heal (tank having trouble with overzealous DPS), I will let them (the troublesome DPS) die, and ask them to focus fire and/or tone it down until tank has aggro. Dungeons are a team effort, after all, and if someone isn't playing that way I'm not going to be sorry. And yes, I do warn people first before doing this...but issues are usually with overgeared, not undergeared players...


And like it was suggested, Berserk + Unchained + Overpower is an absolutely amazing aggro-magnet. I run with one WAR in WP who'll do that and then tab-out til all the mobs are dead without losing aggro (when I run its DRG/BLM, DRG/BRD or DRG/SMN...Doom Spike + BFB + IR is amazing AoE...and yes, the DPS are geared...)
