Our group recently hit a wall in T12 and I'm not entirely sure why. We were making great progress and had even been in the last phase (for a relatively short amount of time) and now we just can't seem to get past Bennu's.

We hit the same wall every time.

A few quick details about our setup: We run BRD, BLM, SMN, NIN for our DPS. We usually push about 5 Bennu's. We also sometimes don't have me, as the BLM AOE, at all because we sometimes have LB3 up. If we have LB2 up I'll throw out a rotation of AOE.

We're trying to push it so that every other Flames of Rebirth we are killing a small Bennu and then moving but the problem with this is sometimes the current Big Bennu isn't dead so we'll have two Big ones for about 10 seconds. Usually the WHM dies or the tanks die when we have one big Bennu and one small Bennu left and then it just falls apart from there.

Is this simply a timing issue that will work itself out? It's very frustrating to be in the last phase a week or two ago and now we can't even get out of Bennu phase. Looking for anything that can help out.
