I actually merged all five accounts, from their own B.Nets to a single B.Net (for a while there, I was thinking of 8-boxing as an option).
In retrospect, it might have been a good idea to move four of them and leave one on its own B.Net.
And then add accounts, such that there are five on each B.Net.

I should call billing and see if I can move one of the accounts.
If not, then most likely I'd go with 8+2.

Not including healers, I think for PvP it is better to either have everyone IWT/in-melee or everyone ranged.
Not saying a 4x DK (melee) + 3x Elemental (ranged) + heals won't work...

The top four teams, were the ones I was most interested in trying... based on what had been revealed from beta and the wowhead stuff.
The Monks & Mages, are for getting the most out of RAF; already have Priests & Hunters, which could be transferred if I really wanted those.
Not that interested in boxing Warriors or Rogues... hopefully that doesn't come back to bite me, as I leveled Paladins and Druids without RAF (because I was fairly sure I wouldn't want to box those, during the first round of RAF).





If your accounts have been inactive long enough, consider the Scroll of Resurrection.
That gets you a character transfer (server and/or faction) or a new toon (at 80th) on the server of the character giving the resurrection.
Playing with other boxers really rocks; <The Zerg> play on Magtheridon-US (PvP).
