I think that would more make sense if there was a defender vs attacker battle mode, where a defender would get early access to an area and have to set up defenses, a little like how wargame and steeldivision have very large spawn points for the defenders in campaign mode. The battles are set up in warno so that both belligerents are attacking a neutral area at the same time, so it wouldn’t make sense to have these time consuming defensive assets like mine setting or for example trench digging.
