Vyndrees post pretty much said it.
I added /use Dark Brewmaiden's Brew to all my toons dps-macros, spread them out (like 5y from each other and 10-15y from the boss+tank) so they still would be close enough to taunt mobs from even if the drillingmachines would punt them backwards. I found that with and without bloodlust made a huge difference, without bloodlust they always got a keg off on my tank on about 20%, but with lust up I was able to just burst down fast enough.
