So I did this dungeon for the first time and it was not good. The tank was taking massive dmg in every mob and with first boss. I don't think he was using any potions or if so they did no good. I always inform my party when I am new to get tips and strategy but there was some miscommunication on that first boss and we had to do it 3 times. The strategy was for the WHM to kite all adds so other 3 could focus on princess. Regen was not keeping up with dmg on tank but with 10 ants & marshal following me I had little opportunity to add in any cures, even with presence of mind. On the 3rd try one of dps assisted by taking out any ants that were doing me dmg.
On sandworm, 3 of us got pretty much knocked out early on but that was all my fault according to the tank. At this point I left....it took me a while to figure out how to do that as I had not done so before.
I am going to read up and watch some videos before attempting again but would appreciate thoughts from other healers.
