I have never used RAF so I do not have a clue to the goodness I am missing out on but my DK-Shaman team is almost 76 and just at 8 days. They started out as a 5x shaman team but that was kind of a pain. So at 27 I dropped the main shaman and started boosting in SM with my pally. At 35 I went to ZF to boost then to strat at 45 up to 58. That was the last of the boosting for that team. From there I ran them with the DK instead of the pally and have quested ever since.

My lock team I ran to 20 as a 5x lock team, and have since dropped the one and have boosted with the pally. They just hit 47 at 2 days played. Most of that without rested.

I used to run to 20 or so and then try and running the team as a team, but that got real old real fast. I liked the Silvermoon quests and stuff and even took the shaman and druid teams out there to hit 20. However, now I have started the new melee 5x pally team (which is really just 4 because the 5th is the booster). I plan on getting them to 10 and then boosting them as far as I can.

It is not really worth it to me to buy a new account just to get RAF and then pay to transfer the toon to my real accounts. With as many teams as I have, I can rotate around and get the most out of rested. Or run the level 8- mix team and do heroics when the boosting gets old. Guess I am just a glutton for punishment.
