Speaking of Byakko, a lot of parties thought I was crazy when I suggested that they let the OT solo the first stack, and then the DPS eat the second stack when the MT is grabbed. A few of the farm parties were very hesitant to try it. Fortunately, there were other groups who ran with the idea and it worked pretty good. But it seems that pre-assigned stacks with the tanks each grabbing aggro is the dominant "meta" strat right now.
