Reduce ME Ore Node frequency, increase Node size
Currently ore nodes can be found quite frequently. Many nodes in one claim area for example. This can lead to many 'gopher holes' in MP. Also, with a steel pick and food buff the average node can be cleaned out in one go.
Reducing the number of nodes to say 1 from 5, and increasing their overall size (especially underground) would:
Reduce the need for ore scouting
Reduce the gopher hole count (Engineer broke a leg again. Gonna have to shoot him)
Increase the practicality of building underground mining complexes.
