Balance in Heroes 5.

Well, there is some balance... Necropolis is definitely weak. In equal numbers, they will lose to anyone, but if you play properly, they can develop quite well... And the Dungeon has some strong units, and in my opinion, their main advantage is the additional skills they have... Although, I still think Elves are better... By the way, I haven't played as Dwarves yet, and my friends say that this faction is completely useless... Should I get used to playing as them and practice, or is it better to continue playing as the starting factions? By the way, is anything known about whether there will be more factions in Heroes 5?
