RAF problem

Hmm... I've hit a bit of a dilemma.

I have one account currently, with 4 battlechest's ready to go behind it. On my current account I have two level 80's that I will probably want to use in two of my final teams. On the other hand, I also want to be able to level up other new characters on that account as part of the combo, ie. 5 mages, 5 druids, whatever else.

On my current account, I have no RAF invites left (I know, terrible planning on my behalf). I've already called Blizzard Support, and they've cancelled the link between one of those created trial accounts in the hope that it will free up another invite. The accounts that were used for those previous RAF invites all have about 50 days worth of link left on them, so updating one of them and then inviting the others isn't overly practical. Currently I've been told that invite renewals only go out every 30 days from the point of the last invite. So looks currently like I might have to wait another 24 days for it to appear.

I was really wanting to have the accounts linked Old > A > B > C > D, but as I've said, this means I have to wait another 24 days at the least, which is crap, because I want to use them now :P

Any ideas?

Also, one of my 80's is a prot pally, does instance boosting still work at this stage?

What is the end goal? 5 box with mixed team(s)? You can link 2,3,4 and boost the teams with the 80. As long as the alts stay near the same level they will get the 3x exp.
To get some new toons on the account; start now with 2 new alts and boost those, as many as you need and then when the month is up you can then link 2 more alts but this time link to old toons.
In 6 months time you will have 50 toons at level 80. Sounds like a long time but think about the best times to 60 now is about 12 hours played. 60-80 is another week or so.

Depending on how much time per day you play, you can have 10 at level 60 in 60 hours or 2 weeks playing RAF 4 hours a day. It does take slightly longer playing 5 at a time but not much. Next month start on 2nd group and level 3 at a time, using one of the new 60 to help.
