I would fix the world generation problem. I would fix the really stupid EULA and don't limit the things owners could do on their OWN server. We have bought our accounts because Minecraft is suppose to let you do whatever you want but not with the EULA here now, yes, I know the EULA was subject to change when I signed up for an account but all they are trying to do is get people to buy their Realms. Mojang is being kind of greedy for money because I don't see the point of a Realm when you make your own server for FREE. I would think that at least everyone has good enough internet to host a 2 player server, with Vanilla. Heck, you cannot customize the Realms yet unlike you can with Bukkit. All the money they have made, would be put into Mojang's Money Account, whatever that is, and build interests off of it so that the company can expand and grow!
