I am about to reroll on a new server as the one I am on is is slowly dieing.

I only dual box, and I was planning on RAFing with 2 new accounts to get the new mount and pig pet, and to get new toons on my 2 main accounts (obviously). Once RAF is over I will be back to dual boxing my 2 main accounts.

My main accounts are A & B, I was planning to setup RAF with accounts C & D as per: A>C, B >D

So I firstly I was wondering if this setup will get me 2 of the new RAF bonuses, and secondly I was wondering if I can go 1-85 just dungeon spamming or will I need a 5th account to make it viable.

First team disc priest, hunter hunter hunter
2nd team Prot warrior or pally, mage mage monk(heals)
3rd team DK, DK, DK, DK
4th team Ele or resto Shaman, Enh Shaman Enh Shaman Enh Shaman

If I do need the 5th account can I setup up RAF to get another 1 of the new pet pigs?

Thanks!
