Leveling from 1-60 with RAF goes very fast, maybe they could extend the time you can level faster with RAF (now it's 60 or 90 days). From 60-70 should be after 3.0 no Problem, because they lowered the XP you require per level and the Outland Quests are not so bad for Multiboxing, because you can now skip all the collecting quests But leveling in WotLK is a pain in the ass, alot of collecting quests and alot of quests you have to do with machines ... boost leveling from 70-80
