I was thinking about it today and i'm pretty sure that if you are willing to pay a little extra money, you can get the character level grants for both of your accounts (In just a 2 account set up). It requires 3 account to do it but in the end you would be able to grant levels to both of your accounts I think.

So you recruit your second account with your first account, then you recruit a third account from your second account (obvious). Then you go about your normal RAF leveling strat for your 3 months on your accounts, 3 boxing. My plan was to get as many classes to 60 within 3 months as i can. This way i can get 2 of every class to 60. SO i woudl dual box on accounts maybe 4 level 60s, at a max of about 2 days /played each that isn't too bad. Your 3rd account characters are just going to end up being dummys which can easily be added to a 2 boxing set up to help you level. Then you level 2 level 30s on your accounts, and 2 level 15.

So now you can grant the 30s on my main accounts to 60, with the 30s i can grant my 15s to 30 then to 60 with my 60s. That right there gives you 2 of 8/9 classes in the game.

Kinda useless in the end but if you are just dual boxing. It only costs an extra 20-50 dollars, depending on how fast you can do it, it doubles the amount of level 60s you get in the same amount of time. Keep the 3rd account for whatever needs you have, sell it, give it away, whatever.
