Quite obviously, they have a very clear vision of how the server will progress just like any relation between a project and author.
Very few suggestions will fit into that frame.
I have a very clear vision for the server, this update is just a stepping stone compared to what we have planned for the future.
If we end up going as far as I would like I will probably move away from the 'Fort Wars' name, because 'fort wars' is a generic term on blockland and refers to so many other similar servers; I want this one to stand out of the crowd.
Also I turn down a lot of suggestions because they wouldn't fit the current/planned gameplay, but many of my ideas for the server come from them. A few examples are things like UAVs, Attack Boats, Stationary Defenses, etc. Even if I don't use your ideas directly I usually take bits and pieces from it depending on what it is, and I try to fit it into what I have planned.
anyway its 1am im tired and I don't even know if what I am rambling on about right now makes sense but whatever
