For the AoE rotation: If there is a BRD in the party you get the best damage per GCD if you have them maintain Ballad while you cast Fire III > Flare > Blizzard III > (repeat). In doing this you are basically just using Fire III to activate AFIII, get many Flare casts and MP back with Blizzard III after a tick of Ballad. It's great for WP SR's, shaved about 30s off each pull for our group when the BLM switched to that rotation from the "standard".
Haven't tested how it would play out just with Fire III > Flare spam as I'm not sure if Ballad would give enough MP to maintain that.
