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

I mentioned XL because it's very difficult to fully develop a Castle there; it takes less time to develop other castles. Also, due to the cost of units, although it's not certain that enemies will have Ultimate abilities. This refers to how many monsters, chests, and other modifiers should be on the map so that enemies reach level 30. And even if you play against the computer, it definitely won't reach the point of having Ultimate abilities.
