If the servers merge you will be with the other players from other servers, but otherwise you can't change server, and the merge will happen, so don't worry about if it will ever happen.
No. If you could change players from servers then players from server 1 can bring there character into a brand new server and surpass everyone.
Though I do agree on having a Global server, that would be pretty cool IMO.

Actually no you wouldnt because the strongest would be even stronger and no one could beat them, second strongest would be next and those learning game and wasting cash for vip 10 just at the bottom.
