Delve2: Haste2/Dia3/Frazzle2/Distract2, specific nukes on specific mobs, debuff removal, on some of these mobs I'd prioritize missing aoe debuffs and removing them from others, something complicated by receiving these debuffs yourself by being on the front line.
Haste2 recast every 5 seconds? With March and without composure, cast on yourself, probably, but cast on someone else and maximizing duration (IE: Abyssea Gear + Composure, probably looking at more like 8~12 seconds)
