Balance in Heroes 5.

2
3. When playing on large maps, and in any prolonged game, Haven will dominate with mass light magic and hordes of cavalry.

Exactly. Isn't that an imbalance?
Of course, the rock-paper-scissors mechanic, taking into account the map size, is cool, but it's still not as good as it could be.
And when I said that the dark elves are weak, I meant that in the final battle, the coolest thing is to use combinations of hydras and girls with glowing swords, along with riders on dinosaurs and their lizard-bite, but the problem is that the last pair can't withstand a hit and dies at the speed of an electron emitted from a synchafazatron emitter, and that's their main problem. But I really like them.:smile05:
And the same goes for the dwarves. They are just too durable. And with the Tower, it's difficult to take their city on a large map, even with Haven's cavalry, and the battle will be in a well-developed city, which is an undeniable fact. Without the Tower, I agree, they are a normal faction, but with the Tower, they are terrible cheaters, and it's hard to argue with that.
