In your opinion, which faction is the strongest in Heroes 5? Let's discuss the advantages and disadvantages of each faction.

It is impossible to say with certainty which faction is the strongest. On the largest map, perhaps Necropolis is the strongest. By the time you reach the enemy, you will have killed a lot of neutral creatures and gathered troops for yourself. But personally, I think that Fortress can defeat Necropolis if the latter doesn't manage to gather many troops before the clash. And in most cases, I prefer to play as Dark Elves.
