In Warcraft 3: The Frozen Throne, the reason why the Warcraft 3 Dragonhawk Knight is not as good as the aircraft can be referred to as follows:
1. In the game, Dragonhawk Knights are not only expensive to build, but also require a high population of 3, and the build speed is relatively slow.
2. The cost of aircraft is much lower, and it comes out very quickly. It only accounts for one population. What most players want to do is to annihilate enemy air units in the shortest time at the smallest cost. Under this situation, it is inevitable that human players prefer to use aircraft with low cost and fast molding speed.
