The limit is still 8 per bnet.

Regarding removing accounts, people were buying BfA for the boost, then removing the account, if I recall correctly. I'm expecting you can remove accounts.

Am I excited? Not really. See my other post where I got all the rewards from the previous RaF, back in June.
The rewards I'm interested in are the mounts, and (to a lesser degree) the pet, and free months of subscription.
Titles, Tabards, Attire, and Cosmetic Enchants are wasted months, from my perspective. I'll need more information on the Ruksack... is it an heirloom? how many slots? etc.

To me, it feels like they are really botching the RaF transition.

It would be cool if they gave people who had leftover old-RaF-rewards credit for the months of the new system.
Any mention of that? (For the benefit of others, not me.)

Even though I have them now, it sucks that the 5 old-RaF mounts and 4 pets are now unobtanium. Any mention if those mounts and pets are available somehow? Even BMAH would be ok.

Are you saying the XP boost has been fixed to stack with heirlooms again? (Or, if not, that the XP boost is back to a large multiplier like it was a while back?) Is granting levels in the new system?

Even though I'm not excited, I'll probably do RaF at some point.
