I honestly think that they have implemented way too many servers to start with. They buckled with 90 minute wait times at launch and created even more. I think that if they had offered a switch server at no charge instead of cloning servers, it would have worked out better.

Right now I am playing on a medium level server and scenarios are rare to come up. We would actually enjoy a cross-server scenario scene.

The only negative I could see would be if the two servers would have similar names on them.
