I have had RAF for a little over 2 weeks, and while I have not played to much so far I have gotten the following :

Mage x5 - 1-60
Hunters x5 to 29
Warlocks x5 to 38
Shamans x5 to 18
Druids x5 to 16

Im personally not working on any professions, my main goal is getting everything but the druid to 60 before my triple xp ends, and if I have enough time after that also the druids.

I would also like night elf hunters on a high pop server for shadowmeld fun but I most likely wont do that just from boredom after all these groups.

It is awesome though, I wanted more groups but i dreaded leveling again, this makes it fun because you don't even have to do all the kill quests, you can literally just pick the easiest ones to do.
