Quick forey into Azhera for a couple of quests. Note, you need to finish Lim-yo before you can do the Archmage turn in. You also have to run to Orig, UC, TB and Ratchet to polish off the followups. Unlike UnGoro, this area did require me to be 51 ish to do well in the north part. Keep an eye out for berries - nice +10 stam bonus that stacks with aion online gold and food. Also, make sure to batch up quests, lots of running from north to south that you can better maximize your time. Do the Salve quests at least once for the XP. The escort quest out of Jaelinar is not hard with a team - but have everyone right click on key first Note the elite quest Verrifying the Corruption is not elite and easy to solo.
Good grinding near town and just west of town (and lake KelTheril) - better than Azhera, imo, since graveyard and town is much closer - but it is 2 hops from Orig on bird. Again, heavy grinding - you may be finishing up these quests up to level 58 (some are level 60 quests that require teams)
