Which faction do you like the most in Heroes of Might and Magic IV?

I don't have that impression... Haven has many problems. It's easiest to play as Necropolis, after all. Sylvan is also...

What about Haven's spells? What about the Djinns?:D
No, it's easy to defeat neutrals with this faction. You don't need to think much: just use magic and that's it.
But with infantry, you need to use your head).
