First off; thanks for taking the time to help out!

I just began multiboxing(5s) again tonight after having a long break from my last and first time.
My characters are only lvl8 at this point after having finished the 1-5 Durotar quests, now my question before I go on is; is it correct that 5-12 is in Eversong Woods? And then Ashenvale (I think it was, after ghost place) and THEN barrens at 25 or something?
I'm just a little confused seeing as how that is _a lot_ of running around and seemingly a slow way to go about it?
Granted I've never used RaF before nor have I leveled an entire multiboxing team before (my first time I only got to lvl15 before quitting due to lack of beast computer etc), but I have leveled a lot of characters to 60+ (mainly 1-60 pre-TBC though, so sure a lot has changed) and yeah.. never went with that approach.

Just wanted to make sure before I go on, so as not to waste my time seeing as how there are more resources out there for leveling quick.
