At the moment, you only see 16p server, because its an evolution server. Basically, the server starts with low number, but will expand gradually following number of players. So the server have no problem supporting 64p.

As for the VIP list, its on EA side that keep delaying on VIP list. How MBT be able to give VIP list if its not even there?

I hope this can give some light into your problem. My apologies if my answer isn't acceptable.
