I should clarify.

7 hours and about 12 minutes is my fastest RAF boost time from 1-60, but that included a Warlock summon chain so that it was pure instancing the whole way with no training or running around. That includes the 1-10 by hand, which takes an hour or so. I could probably shave a half hour off of that time if I ran my DK and had someone else MB the alts so I didn't have to worry about them.
