noI think incorporating just a few more unit abilities would be cool. Raises the skill ceiling a bit and adds some fun micro. Some that come to mind:
-Give swordsmen line charge like zealots in sc2. Alternatively, give them the ability to raise their shields to take less damage from arrows.
-Monks heal a small radius of units (you'd have to choose between using monk juice on conversions or healing)
-Groups of archers fire a volley of arrows at a targeted area
You convinced me, I actually wouldn't do those things anymore. Micro is bad and man at arms are fine as is.
