I split your topic from the other one because it was old.

As for boosting... Ruby Sanctum no longer works, and the age-old method of running dungeon after dungeon is the only way that I know how to do it. However, to be fair, boosting has never really appealed to me all that much, and unless it's for just a single team with RaF, I'd much rather either run a mixed team through dungeons with the LFD tool, or quest with a team that doesn't meet the LFD requirements.
