So, I couldn't find a thread about this in here, so hope I'm not stepping on anyone's toes: I notice that that at the moment, combat fabbers will assist with construction of units and buildings that happen to take place within their range. This is a problem if I have set my rallypoint close to either a factory or a large building in progress - it makes my economy less efficient, regarding the metal-energy ratio. So, I think combat fabbers should only repair damaged units, possibly damaged buildings, but never anything in construction. Thoughts?
