I am going to 5 box and the 4 new accounts will be throwaway accounts once I hit 60. My plan is to get as many 60s on my exisiting accounts as possible before the RaF expires. I also want to get some 60s on other servers due to my exisiting server has 2 accounts which have nearly max characters on their accounts on this realm.
I may also split this endeavour into leveling 2 of the newly purchased accounts at a time, this will still give me 4 toons for each toon to boost with my druid
So my linking will be
Old account 1 - new account 1
Old account 2 - new account 2

later I will then use the new accounts 3 and 4 in the same fashion.
