If a tank loses aggro, whose fault is it?

Oh of course, in the OPs case, that tank was garbage and so was his blm friend.

A good tank would establish a good lead on aggro first before touching their dps stance, that's a no brainer, but Once hate is established they should switch to dps stance for obvious reasons.

I haven't done any dungeons at all in weeks (all I do is raid n pvp), and when I raid with my static, we want to keep the mt in dps stance as much as possible without her having to use powerslash too much to push raidwide DPS. We do this through communication and use of cooldowns + me not using BB if I'm one BB away from ripping hate. If I use butchers when I could of used storms eye instead and rip hate from MT and the boss turns around cleaving the raid killing us all, that would be my fault as the offtank.

That's one of the few situations where it's NOT the main tanks fault for aggro loss.
