Tonight was my first time playing, so maybe someone already posted on this but I think it would be easier to distinguish the units with a unique symbol besides all units having a circle.   In the thick of battle or looking for specific units you need to move to another army would make reconfiguration easier, especially when you are zoomed out so far.

Also, figuring out the tech has been a challenge thus far.   I am sure it will come to me in due time.   Also, I use a 3 monitor display setup in Eyefinity.   It would be nice to adjust the UI to move stuff to my middle screen instead of having to move to my left or right screen all the time.  

Hope you like the suggestions, I am sure there will be more bug posts and suggestions along the way!
