WWS parse. Check Anetheron death. Fight may be a bit harsh to ranged since they change targets to kill the infernals, but it shouldn't be too big of a hit. Would probably hurt the fire mages though; I am not certain, but I think the infernals are immune to fire.
I've only recently started to care about my dps, being primarily a tank, but my guild started to complain, so I made some changes. My post about improving my cat dps isn't that far back in this thread, actually.
