And the defense of Orc units is terrible!!! And they have very little health.
Everyone knows how quickly Berserkers are destroyed without rage.
Goblins, Centaurs, and Orcs are very poorly protected against rapid destruction. Shamans are slightly better, especially considering the low health of Berserkers.
But how are Orcs supposed to defeat Lava Dragons???
Contrary to the opinion about Black Dragons, Lava Dragons can be considered the strongest creatures of the last level (40% of the damage is reflected).
