How many factions are there?

I agree here... a drawback of the fourth game is that many monsters were moved to other castles... but overall, the fourth game is a step forward for the Heroes series.)

I generally don't like when animals are placed in castles in games (for example, wolves in Heroes)... they should be neutral (like wolves and bears in Disciples)... or they should create riders (for example, dwarves in Heroes, and dwarves in AoW2)...

P.S. This doesn't apply to mythical animals (unicorns, etc.)...
