I really don't understand any issues people have with AK at times, if the tank left because he thought the dps was too low then all I can think of is that the DDs didn't have the bare minimal of the level 45-50 class quest gear and the level 44 company weapon at minimal, everything else simply doesn't matter for the most part as I did it with a few low level trash accesorys and the gear i listed, also had a DRG with the same gear as me (don't know on accesorys) and we still got the instance beaten, I've mentioned this on another thread before but damn...AK really isn't that hard.
