Hi I've read this quite a few times and it still confuses me. I'm just struggling to grasp what you believe our current build team does.
I help lead the build team at CubeCraft, we have a great team of truly talented builders who create content daily on our build server and we are actively recruiting. Maps take time to create, and are always released as map update or as part of an update.
This year alone, we have released 125 maps, along with 8 lobbies. That's more maps than any other year.
As for the little updates that "the builders don't have time to do" could you please explain what small changes you mean? I'd be more than happy to make the changes if it's a good suggestion.
For example if you check news posts I've made, I always add a full changelog at the bottom listing small changes that have been made. These are either suggestions I've read on the forums, been forwarded from staff or a map bug.
