Possible expansion improvement on all units:
Weapons range slices rather than circles and hold position behavior adjustment
You know when you hit alt or hover over units you can see the circles that represents their weapons range? Why not represent them as pie slices instead? I feel the circles can be improved in this way to encourage better micromanagement of fleets. You could represent their weapons damage statistics on the info card in colors and the represent those respective weapons around the ship as pie slices so players could see them and could manage how to use them better( because we all know that most ships cant fire in an area directly behind them.) Some of course would remain complete cricles (like starbases), but their repective weapons ranges could be visible (since they differ). Also, if it seems like a lot of additional calculations would have to be made, and thus slow down the game, you could make it so you only see that on your own ships.
Also to help utilize this you can make it so if you set your fleet on 'hold position' and tell them to move within their firing range they rotate to face that position rather than move towards it (as if you were attacking something).
I feel this could drastically improve the experience in battle and incourage more players to be more invloved with the battles and be rewarded for their focus.
