Hi

Is it your rotation? I’m a level 68 BLM currently and use this:

Single monster: blizzard 3 > enochian > thunder 3 > blizzard 4 > fire 3 > fire 4 * 3 > fire 1 > fire 4 * 3 then repeat.

Multiple monsters: blizzard 3 > enochian > thunder 4 > fire 3 > fire 4 * 2 > flare > transpose > thunder 4 * 2 then repeat. I guess I can add foul when I unlock it

Not sure what my dps is, but dungeon runs seem to go ok.
