I agree. It would be much better if we could trade with every one and raid with every one. There should not be a server restriction anymore. I found some really great guys to raid with since they allowed cross realm heroic raiding, but Blizzard is going to stop this with WoD for no reason. It doesn't make sense why you should not be allowed to raid cross realm mythic in WoD.
WoW today should feel like one big server and not several very small ones. There are probably 2 or 3 server which seem to be alive
