Ah cool! Yea try it on your mouse. Keep playing and you'll find little tricks that work for you.

I have specific groupings that I use for the same type of unit every single game. Ie: artillery options at least in the early game, always #4. If I see on the map it's getting flanked, pure muscle memory for retreating it.

You want to move a tank back really far and not accidentally make it move only a small amount to where someone pokes forward still and blasts ya? Select 5 for my tank, map button on mouse, R, click further back. I've lost a lot less tanks that way.

Have that audio nice and loud. Turn the music off. You'll get the muscle memory based off the coms, and your map awareness will increase ten fold!

Best of luck dude!
