RAF is super fast from 1-60 but ONLY 1-60 as you lose the 3x XP bonus and don't get any more fee levels after 60!

So it's worth it if you plan on leveling up a bunch of 60's. But if you have 5 accounts already and they are high level then don't worry about it as you won't get much benefit after 60.

If you can't stand to level 1-60 then just buy a PL for the accounts to 60 and play 60-70.
