How is this going to work? Are US and EU players going to be completely seperated via separate clients, or will both have their own megaservers you can choose between, or are both sharing the same megaserver?
Forcing a complete split between US and EU communities was something that bugged the hell out of me in WoW. Other MMORPGs have at least allowed players a choice between US and EU servers, and I hope TESO offers the same choice if I feel like playing with some American friends.

you will still notice it, we'll not sure how your playing but you need to move about and keep track of your enemy moving and jumping about the place, ie fast movements and a lot of them.
