I did

Existing account 1 -> Referred account 1 Referred account 2
Existing account 2 -> Referred account 3
Existing account 3
Existing account 4
Existing account 5

this way i can use accounts 345 to boost (got a mage druid and a priest, along with 3 warlocks i can boost/summon with)

But the biggest thing for me was having 2 accounts referred on my main, because of the gifting every other level thing. This way I can level whole teams to 60 and create a new lvl 1 and "gift" 59 lvls all at once and have a "free" 60. I want one of each type of tank on my main account, along with some others, so this lets me have that with minimal fuss

I'm wondering now whether I should xfer the toons from accounts 345 (7 toons total worth saving (> lvl 50) to the new RAF accounts, xfer the toons from the RAF accounts to the old ones, or bite the bullet and get 2 more after the first RAF accounts are used up. (more free levels, more exp boost, and 10 boxing potential)
