if it anyne wants an example, a free and paid hoster im using as well charges for bungee servers, and they are pretty cheap. obviously you have to pay for each server, as each server is not a world. mh probs has a plugin that auto creates a server for players when they want, and that costs money, if they dont have spaces already.
personally i think this update is okay, ive seen a lot of people comment about loasing their server completely. i wont be surprised if a few go to valknet instead
