suggestion

refer a 4th account though RAF (cost 30-40 $ for software)

10 free days + 30 days for RAF

lvl 2 new toons with Pal power lvling them to 60

should take you less than 20 hours play time. 1 or 2 weeks game time?

You do not pay for the accounts for 40 days.
lvl more toons if you so desire. gift lvls to your vet account.

at end of 39 days cancel new RAF account

cost you 40 and you have aleast 2 new 60s
