I usually always do the standard--- T3->F3->F1....(till about 400MP)->B3->T2->F3->F1....rinse repeat. I only do Flare combos when we pull large mobs or in a boss battle who spawns adds this way I can hit the boss and the add. However, in boss battles, after the first F3 I do Raging Strikes. Not to mention you have the T3 and F3 procs in-between. I've never had MP issues and have pumped out some nice DPS doing this on single targets.

As for mob movement, that keybind is an awesome idea!! Will definitely make things easier.....OH! And depending on how quick you want to burst (especially if no Flares are being planned to be used) depending on situation I may swiftcast the first T3 or F3 to get my rotation moving quicker.
