I've been "called out" twice now for having low DPS in boss fights. First time was on Ultima HM about a month ago and most recently was last night against Leviathan EX. I really don't know what I could be doing better, is the only problem.
I'm i88 with my normal build. Elder Staff, Evenstar Cloak, Crimson hat, everything else Myth and Allagan. Eating Buttons in a Blanket, normally or Stuffed Cabbage on Levi/T4+5.
For mob packs I have no doubt I'm in the top tier. Flare spam rotations are my bread and butter, so there's no issue there. It seems to be single target DPS, especially burning down the Spumes on Levi, thats causing the problem.
My rotation is: Fire3 > Fire > Fire > Fire > Fire > Fire > Fire (all blowing Firestarter procs as they appear) > Blizzard 3 > Thunder 2 > [Repeat], blowing Thundercloud procs as they appear.
Thoughts or suggestions? On Levi I was below the ACC cap at first and tweaked some gear to fix it, but still didn't help.
