The whole comment was about the absurdity that giving the BLM dps buffs cost the raid more dps. You're getting off on a tangent. It is completely obvious that you should have the lower dps deal with mechanics to minimize loss (and surprise here, everyone else can move and attack so it's not even a good idea in general to have the BLM deal with movement related mechanics). But then again, the AST should have given those cards to the BRD, clearly. Bard should never ever play foes requiem. The ninja shouldn't use trick attack or else his teammate may do more damage. Are we really complaining about raid buffs? Might as well say the bard and machinist numbers were inflated because there was a dragoon with disembowel 100% of the time, catering to the ranged to inflate their numbers.
EDIT: lol double dotting. So you take one global cool down from hitting one enemy and spend it hitting another. Sounds zero sum to me...
