Multi-tank busters should apply to the main tank in an alliance instead of a DPS

[aodhan_ofinnegain]

that is false information, ALL 3 tanks need to have their stance active after the tanks are done with their opener
how are you a lvl 80 warrior main and not know this?

I'll second that this is completely rubbish, I've often been an OT in alliance without stance and still taken the intended simultaneous tankbuster while a couple DPS were ahead of me on the aggro list.
