Once the blms are geared 2 is redundant, they compete with each other for aoe damage when a single geared blm and a bard can wipe out any pack in a single rotation. Any more than sufficient aoe to kill everything before the blm has to go umbral is wasted dps, and foes plus holy from the whm can be enough while the bard and blm with correct cd and song usage will deliver far better single target rather than 2 blm.

8:40 soldiery runs last night with this setup.
