Will you still be able to buy stuff from the store for the old survival world? You seem to not understand that the old survival is not going anywhere. You will still keep everything in old survival, which will still be 95% functional as a server (minus creating new factions & auto-disbanding old ones). If you want to dominate 2 servers at the same time, you pay twice as much as if you wanted to dominate 1 server. It's simple math.
