So you created a character on a different server to your friend and now you want to swap so that you can play together? I'm sorry, but that's going to cost you! Changing servers is expensive... didn't you know? At a technical level we have to change one field in the database. That's expensive work... so that will be $25.
What do you mean your server is at a low population and you want to change because it's ruining your gaming experience? $25!
You're sick of being ganked on a PvP server and now you want to swap to a PvE server?? Oh... that's too bad. $25 please...

You get my point. The greatest con job in the history of MMO gaming would have to be charging for character transfers. There is no reason why the whole process of transferring a character from one server to another can't be automated and made seamless so that a player can move from one server to the next without a cost or hassle. So why do companies like Blizzard and Mythic charge for the service? Well there are in fact a couple of reasons, but the main one is more $$. I can't actually think of any downsides to allowing players to migrate around servers freely, aside from potential overcrowding. Beats under population in my books.
I think it's funny that Mythic wants to charge for character server transfers when they are having so many server population issues. I also think it's funny that they copied the con job from Blizzard and expect to get away with it (actually they probably will). I suppose they have to earn a few extra bucks on the side...
ArenaNet have already announced that Guild Wars 2 will have seamless server transitions for characters built in as core functionality. No costs involved. It will work similar to changing district at the moment, except you will change server. There are no hassles with conflicting character names because names are unique across all of GW2. They achieve this by enforcing something called a 'last name' for your characters upon creation. Incredibly this allows for more than one person to have the same first name for their character... who would have thought it possible? Not Blizzard and not Mythic, that's for sure.
