Miners can only be built on the edge and the patches are super low density; omnic water is only used for research and water (which is weird considering it feels like you can turn practically anything into); AAI miners are kind of slow for most production, mining drones still need placed regularly...
Am I missing something? I kind of expected a technology that allows making omnite from omnic water at some point but no I'm currently stuck with the problem of trying to get enough omnium to get all my production done.
