I have 3 account and I intend to upgrade to 5 man boxing. Therefore, I need to get 2 new account.

I can't decide which account A, B, C to link to the 2 new account. Will it be better to link account A to D and E, or link account A to D and account B to E and leave account C without any RAF xp bonus.

Any suggestion given will be appreciated. Thank you.
