Nice guide

My personal preference is to only do RFC until level 10...then go to Wailing Caverns. I do that until 20 then head to SM. Rather than doing SM in the way you've done, when I arrive, I do GY, Lib, Arm then Cath.....only for the achievement. I find that the GY isn't XP efficient and as I'm using a demo lock to do my levelling, the demon kills many of the mobs before my DOT has had a chance to "tick". From there on, I do Lib, Arm and Cath until 40.....I do all three to increase the times between resets to make sure I don't reach my limit.

I hadn't considered getting a trial of TBC to do the ramparts at 55 though...good call as my last team is 53 and I'm getting sick of the site of Stratholme!
