I've just been running instances as my 5 shaman group, I didn't even bother picking up any non-instance quests. Currently halfway through level 73 with about 12 hours of played time, not sure if thats good or not but the non rested levels seem to be progressing at about the same speed as I remember 60-70. UK is def a safe bet for exp, first boss drops a nice MH 233damage wep too if your guys are geared crappy like mine are... its an easy and fast clear for 5 shaman once you get familiar with the pulls/mobs/pathers, very first run took me over an hour to get to the last boss...a few runs later it was taking 20-25 minutes for a full clear (last boss I still sometimes wipe on and just reset when that happens) Nexus im in the process of learning atm, exp right now isn't as fast but change is good...so sick of UK now
