Thanks Zaft for your input .

Well previously we didn't know about pushing Twintania to P2 at a specific timing, so was pretty messed up =\ (IE, Fireball then straight DS, cant precast SS due to medica 2 casting, or....DS happens after a conflag has been burned down, I gotta choose between healing those DOT damage in preparation for next fireball, or prep the tank for DS).

But now with proper push timing, I don't have too much things at once on my plate, and can focus precasting SS for DS .
