There would be more humans, if humans joined, but most people don't use the portal server browser or join. You can't enforce a 16-player minimum experience against bots, because it will never populate. The one person would just leave after a while and no play would be done at all. Without a method to funnel people in, the demand is not currently conducive.
Likewise, you can't really enforce a human cap effectively either with the tools available. The only way to enforce a human cap is use the server bot options, which messes things up regarding solo start. Thankfully (not really), the servers rarely fill.
Experience ZH6YV is down for updates ( :D ), but the same experience ZGQ1G is up. The update submitted is more attack and defend objective voice-over orders, and a scoreboard counter that counts how many times you engage an enemy objective, to keep people motivated. The hope is to make the experience more engaging. And, also, I changed the map rotation a bit.
Should New Sobek City be added?
