Yesterday I had to specc ele on ultraxion since we we're lacking damage dealer (4 healer, 4 dps, 2 tanks...). Has been a while since I did damage in a "real raid-fight". And my dps was rather low for my itemlevel of 395 (though its mostly resto gear, see below.)
This is the specc I've used:

My Gear is 90% resto, so there's not much I can do about the 17.4% hit or the high crit rating. The T13P4 bonus is very nice for ele though.

I do hope I'll be able to heal tonight on our next tries.
I switched to ele somewhere at the 4th try, but it took some time to get into the rhythm and getting used to fading twilight.
Here's one log:
http://www.worldoflogs.com/reports/h...=11490&e=11777 (you can switch to the other tries as well).
The mage was logging, so it might not be 100% accurate.
I do know that my flame shock uptime was not perfect. And on most tries I did not use the 2nd volcanic potion (I was delaying it for a second fire elemental.)
Looking at the logs I wonder if using thunderstorm for damage was stupid on a single target fight.
What I did:
- prepot
- use EM at pull, even though we had heroism as well. but delaying it for ~45s is a waste I think.
- drop fire ele and if available earth ele once power torrent + dmc:v procced
- normal rotation
- use EM and the T13P4 Resto whenever off cooldown, but not at the same time and not when a hour of twilight was imminent
- in the macro for the action button I had /cast earth shock and /cast unleash elements, though that didn't really work according to the logs (or the mage always switched earlier than me)
