Random thought popped into my head just now - have any groups tried cheesing no-death and speedrun achievements by using four nightblades and permacloaking through dungeons from boss to boss? While you shouldn't generally be dying to mobs, there's plenty of elites that can one-shot you if you're not paying attention, and even with high DPS it takes time to slaughter everything in your path.
If you wanted extra cheese you could even run high-mag regen and sneak bonus sets between bosses, and swap to full DD/tank/heal spec just before each boss fight.
Cheesy? Yes. Fun? Quite possibly.
Thoughts?
