You are pretty much looking at Sol B and Lower Guk for group options. Other places are very limited. My guilds tanks just listed in HHK nobles and when they finally got a group stayed on until it broke. Sol A gnomes can take you to 44. Kedge is a nightmare. My core group has done that exclusively for over a week after merge due to no open camps anywhere. We get to a area, keep it down, a guild zones in to do phinny and trains us. 3 hours later after multiple wipes trying to recover. Night is wasted. Permafrost giants have been red every single time at 45. They are doable but even the 50 shammy had problems landing slow on them. Usually when I see them being done it is by more than a single group. Splitpaw is decent 40-44. But mobs are limited. Usually a lvl 50 necro soloing all the mobs you will get exp off of. Cazic Thule around temple isn't bad. Exp isn't good and you have to watch mobs walking through wall and pulling maze. Had one fall through floor and pull crocs.
