Its sometimes hard to beat an opponent if he have 100% hit chance on your flying units (without antiair) and you have 0% chance in hitting them. Also its stupid that you cant decide on who you want to strike or siege, sometimes a unit has 2 healt left and is dangerous one (strike all 2) and its neighbour has 8 health left and 4 more turns to get in action but it gets striked everytime ...
