Barrier

Barrier was in springrts in TA (not ota), so teams could do something like grace time to build up for 15min, and then go.

Barier is set between both teams in middle, its not passable by units or bullets.

So maybe implement it as a modoption someone? Its already oout there in the wild, just needs to be ported to zk infrastructure. Ideally make it like 100 metal units can only get through barrier that is set 15minutes...

Barrier, or any other "no rush" option just makes game long and boring. Basically you are throwing away the entire concept of early game.

This map probably does mostly what you want: http://zero-k.info/Maps/Detail/30553

Fix it up a bit and make a mod out of it.
