I will try the different opener to see if it helps, but it's hard to imagine that changing my order of casts and not getting that second Bio under Raging Strikes would actually increase my DPS.
I can understand that you would do much more damage than me considering your gearset.

But Sunako and I are nearly identical other than ~ 2% Crit Rate and I have more Spell Speed, yet they can pull amazing IMO damage. (*** I have to swap gear around for FCOB for accuracy till I get that stupid Casting Hat)
My Opener. Ifrit Placed next to the Dummy in a position where I don't turn away when using pet buffs)
Shadow Flare (activate AA near the end of the cast)
RS, B, Rouse/Spur, M (Crimson Cyclone), B2 (Flaming Crush), R2 + Fester + Enkindle, Ruin, Ruin, Ruin, B + Fester (waiting for ~1/2 before Fester so that Bio registers), Ruin, Ruin, Ruin, SC SF (fester + Aether Flow), M, B2
That's about it.

Tried Opening with RS, B2, M, B, SC SF but the most I could get was 345 (SMN Only) just over 3 minutes.
