The game has great potential. Initial impression is good, and there seems to be a lot to come, I look forward to watching it evolve.
If the purpose of this game is to focus on the battles and not so much on resource gathering and base building (which is what i inferred from the FAQ and game description), then some consideration should be taken to limit Micromanagement requirements and their needs. Here are a couple of my thoughts about what could be done to address those issues.
1. Engineers. Get rid of them. Buildings and such, see 1a. For repairing, right click and repair (which drains resources and possibly slows production or movement?). Limit # of concurrent construction projects based on either a tech upgrade, # of Zones you control, or some other factor.
1a. Building buildings = select the build option from the nexus (or construction hotkey), and plant the building, let it self build from the resource income you have. Must either have local zone of control or a military unit within range to provide ZOC for the ability to build. Alternatively, you could just make it "if you have sight, you can build".
1b. Extractors = Autobuild all resource nodes after a specified period of time after conquering the zone they are in. This provides long term benefits to controlling zones for longer periods of time.
1c. Amplifier = Same as extractors, longer delay. Possibly multiple levels of amplifier for longer duration of control. Makes holding your control zones that much more important, and makes highly contested zones worth less. Swing zones would have less global impact on economic power, whereas hitting someone hard and deep would have a much more massive economic impact.
1d. Quanta Generator = Eliminate the ability to build multiple quanta buildings. You build one (or none and include it in your nexus), and then get x quanta per additional zone you control.
1e. Factory = One size fits all. One factory building, builds everything. Unlock higher tier units with tech upgrade or Zone count.
I know, this sounds like a complete change of the game. This is my humble opinion on some options for limiting micromanagement and letting the players focus on building military units, fighting the war, and controlling zones of the map.
Keep up the good work gentlemen.
