What happens to VIP accounts for AT?

I was a global VIP on AT, I spent a lot of money on it, and after the merge...I've got teleport commands on the wotlk server because everyone gets s8.

Is my donation completely disregarded save for this little bit or will I eventually get my benefits on the Cata server? Will the cata server get the AT core and will I even get my VIP back if it does?

I fully support the merge but this is a little kink in it that bothers me, that's all. Any info on this is appreciated lol

(I don't even get donor xmogs ;w;)

Well the money you spent granted Full Wrathfull to you in the past and also after the merge untill the Blackrock's change of July so they weren't wasted and, as you said, now you still have some commands on Blackrock.
About your question for Cata, we are going to have the AT Cata Core for Warsong "soon" but they didnt mention if old Vips will be able to use their commands, we will find out once they implement the AT core I guess.

Yeah I had global vip for a minute sure, but at the same time why should it go away? It wasn't cheap
