I prefer wyverns; in my army, they represent the strike aviation (respect to the 4th Guards Fighter Aviation Regiment!). They stand out due to their maneuverability (the most important skill), resilience, and decent armor-piercing capabilities. In battle, wyverns play a secondary and supporting role, as the mighty gorgons serve as the heavy tanks (that's why the developers gave wyverns a searing attack and attack skill). These WYVERNS are like Il-2 aircraft.
