Well we did the dragon tonight, tho it took us ages!
The hardest part about this dragon was actually getting to the lair. Afterwards a few of us agreed it might be easier all around to have a group or two pull all the agro from the passage, sprint quickly to the lair... meanwhile some rezzers follow behind and log away from the door in the lair ready to rez the pulling group (making sure that everybody dies in a neat pile for ease of rezzing).
I had read somewhere he takes good damage with Thrust arrows, we had a scout with us and he reported they weren't actually doing damage. It's also hard to pet him because he has an energy shield which kills the pet spam quickly.
The Stomps weren't quite so bad as I expected, but we did discover it doesn't effect you quite as much if you are behind him, so if you can't run away fast try get behind him because it's a cone not an aoe.
Other than that, a fun (long) raid, something you do just to say you did it... the loot isn't great at all (5 items, not listed above, not very good), the remains are cool and it didn't drop any respec stones.
