It's pretty difficult to push past the 450 threshold on both 10 and 11 if your group needs a good amount of Paeon, which will come down to how fast your group is pushing phases.
@OP: T11: Are you attacking the sphere or cube? Are you strafing in the last phase? Finally, when are you singing Paeon and for how long? Those are the three biggest factors of increasing dps in 11.
