Vulture - good points. I simply did not want to change my unit setup that much by the end of the game. Though I wonder, if you use like a few thousand skeleton archers, won't the dragons rush and all attack them in the first round? AI seems to love pestering the lowest level unit and especiall pestering archers, since they do 1/2 damage in melee.
In AP, Dragon Arrows got tweaked a lot. They only reduce defence by 30% on first level (I don't use archers so I did not upgrade it, wonder what level III does). But there is another way to kill strong stacks in one hit... I love using the Gargoyle (Gorgul)/Gorguana combo. In one battle, the Gorguanas cast Blood Mark (doubles the damage suffered by that stack) on the enemy Tirexes, then my around 320 Gogruls attacked the Tirex (indirectly with their spears through a weaker unit) - they did a critical, Tirexes got some 10.500 damage, all 10 died!
