Thanks for the suggestions. I'm thinking that the more we try harder content the more reasons I have to be level 75 (to improve our groups chance of success since our cleric is pretty under geared). We tried the nro mission last night for PoR and we were only a couple of minutes ahead of the respawn and one bad pull sent us evacing to the zone in and we had to quit at that point because it wasn't worth re-clearing. So it seems dps is an issue as well, maybe I should wait to level until they catch up, I'm really not sure and it's frustrating not being able to make up my mind. Our group consists of me the 71 Paladin, 66 cleric, 66 rogue, 70 mage, 71 druid, 69 enchanter (with a 75 shaman interchangeable with the 71 druid). A Ranger friend just joined us as well, but he's still low (59) and we have some work to do with him to get him caught up. Most of these characters aside from mine (Pally, Druid, Shaman) have zero or under 50 AAs.
Where can I find out more about those missions? Brains and the one in EJ?
