theres a difference between knowing ways to improve servers and actually making those servers from scratch.
Like I said, some people don't enjoy the management role, but they do like giving advice to other people to make their places better.
I host my own servers all the time with friends, I can be the player and the manager. So don't say that I'm not doing anything and have no room to talk. I talk from years of experience and I know you have no room to talk. It's much easier now than it was in v9 to make a server, anyone can do it. I could host a listen server from scratch and have a lot of fun with little prep and low maintenance (it's a listen server, not a dedicated server). So don't give me your garbage excuse that no one wants the management position, because it's a moot point. You don't have to be a "manager" in order to host a listen server because it's temporary and lasts for you and your friend's enjoyment.
Like I said, not everyone is willing to take the time and resources to make a good server, hosting a server requires decent internet which some people may not have access to.
and sure, you had fun with it, but did anyone else have fun with it? did your server actually get a playerbase that wasn't you and your friends?
also no matter what as long as you're hosting, you're the one managing the server, you're the one who has to ban people breaking the rules and appointing administrators for the server. no matter what you're the person managing the server as long as you're hosting it.
