2. Map tracking: Have it so that we know which map we have beat the AI at and at what difficulty level.
I love this idea!
4. Have units gain rank thereby giving them slightly better abilities (maybe even have the player choose which abilities), One way to keep track of this is unit decals.
T3s are going to have upgrades on them at some point. For normal troops there is the more general upgrades unlocked in research.
5. Damage effects: Meaning that units smoke and'or shoot sparks when they get badly damaged.
On T3s the models do actually look a little worse when damaged, but yeah the damaged states could probably be improved on I think.
6. Guard commands and retreat when faced with certain defeat command. Setting a rally point for the retreating units would be awesome. This could also be used to pull enemy units into a trap.....
Yeah, Guard would be good and so would retreat. Because of the slowdown mechanic, when engaged in combat retreats are all but impossible at the moment. It's frustrating.
7 A rally command. Where you could designate certain units to respond to quick key button and they all rally at a certain predetermined point.
I like this too, so if the enemy get deep in your territory instead of clicking all around the scrambling for all your units you can hit one button and they all assemble at the point you have designated.
