Why can't an army just reverse direction without having to rotate? I know this is a bit off topic, but since it has been brought up, Please stop the rotate. Thank you.
The rotating alone wouldn't be quite so bad if they army didn't prioritize staying in formation while it turns. Not only can you not effectively back away from an orbital, the rotation as a group tends to actual drive the rear of your army further forward before they move away.
But yes, without getting complicated about how to force different behaviours of formations when turning, being able to reverse would work quite well.
On the topic of unit replenishment, how is this still not a thing? Lately, I've been trying to play while trying to manage my units more from the army level, and it feels so much more like how they game should be played as opposed to endless factories on repeat queues and waypoint management.
But, having to constantly manually maintain the units is extremely time consuming, and made rather more annoying by the, in my opinion, ineffective UI for viewing the current inventory and build queue.
That said, I'm not sure the best way to go with this is strictly auto replenishment, that sounds problematic when the army is full and you need to reconfigure the units (e.g. less anti-frigate, more aa when you're not keeping up with air threats, etc...)
I'm thinking one way to go might be something along the lines of an army template, an editable list of the units you want in the army that would be auto-maintained.
