I don't think Mapcore needs to change. With a couple exceptions it's generally a levelheaded, laid back and accepting bunch of people. It's a modest collection of community minded creative types, and I don't think it needs to aspire beyond that. The people who run it already have full time jobs. I think the forum structure could be much more streamlined and the moderatorships less fractured, but it works pretty well for what it is.
EOT has its place, and that place is in EOT. EOT needs to stay in EOT.
