The artificial intelligence of units in OW is insufficient. We have only two types of behavior - free movement and stand still. Free movement is flawed because unit can follow enemy endlessly, as long as it stays in it's vision and it's out of the range of it's weapons. Stand still is flawed because unit won't turn around to shoot at the enemy when it has weapon with limited turning.

Add third state (or change free movement), in which unit will follow enemy, but only in short distance from it's original location.
