I don't like it either, especially in the Conflux. There are practically no archers. Orcs have the same damage as Lizardmen, but they arrive much less frequently, especially at the beginning. To improve the wolves, you also need to improve the goblins. Cyclops are very difficult to build because they require a lot of crystals. Ogres are slow. If you can't build any monsters, then one bird dominates there. The only good thing is that the birds can be improved relatively easily, and you can defeat archers without losses if the hero has the right tactics.
