They should consider adding something similar to overflow servers in guild wars 2. I hate referencing other games like this but honestly despite the fact that I stopped playing the game a couple weeks after it came out the overflow servers are a great idea. I sorta think it diminishes the community aspect of the server but with duty finder and everything couldn't be too bad. Adding more worlds unless it's honestly a butt load will probably solve nothing, imagine when they let people buy the game again.(Did that already happen?) The overflow servers would probably be for the zones like towns and the beginning areas anyway. Make it so if you were in a group you could meet with each other on the same server or overflow server....I don't know I'm no game developer but something needs to be done.
