so im practicing my BLM loops right?

and then while debating how to have my skills organized to help my brain complete my loops and a question hit me.

For the AOE loop,

do you *Fire II (repeating) > Thunder IV > Blizzard II > Freeze > Loop*?

Or do you *Fire II > Thunder IV > Blizzard II > Loop*?

i do the former cause that was i was taught and what the game seems to want out of me but i find myself not landing some of my AOEs cause my target (BLM needs a target to cast any attack) dies by the rest of my party and since i dont have a target anymore the cast gets interrupted leaving me to restart my cast on another enemy. should i stick to damage while potentially getting a cast cut short by a dead enemy anyway?
