They have implemented a technology that allows 5 servers or more to share 1 zone. So when you exit your city and enter the starter zone instead of being able to duel properly or gather at the main town with friends. You will be placed in a zone with 5 other servers.
At the least trying to gather is very difficult low levels levelling their professions have no chance against the 85s of all the other servers. At the most pvp gankers have ganged up together from different realms and are exploiting every weakness they can, right now you will not be able to level on a pvp server, you can forget it. Griefers are causing mayhem. There is also lag and the world is not seamless.
This has hurt low pop realms even more as they cant even produce things for their AH everything goes back to single server structure, including guilds. So you can meet someone and make a friend and then never see them again.
I am against it, I think its a terrible feature. I advise anyone who wants to start the game from scratch to stay away for a while with MOP about to launch the problems are going to be compounded.
I would like to add if this feature was in a group levelling game like city of heroes then it could possibly work well. In a single player self sufficient levelling mmorpg it sucks balls.
This is going to make levelling a monk or your new panda class the normal way a little tricky to say the least and gives those who have bought a 2nd account to grant levels an even better advantage which I find disgusting.
The forums have exploded in the US and EU regarding this. I am not hyperboling and I am not a special snowflake many people are upset, I want to carry on playing my game and hope they put in a feature to switch it off.

My post is about warning folks, if I wanted to come back right now and I wasn't already subscribed I myself would like to be warned.
Instead of a "world" feeling you are forced into what seems like a bad asian f2p game that is instanced and you have no choice of your "world" server. But you pay a subscription.
