The weakest castle in Heroes of Might and Magic IV!

I find that Haven is the faction I play best with – slowing enemies down, the ability to teleport enemy units across the battlefield, and having 4 ranged units (I usually have 3, as I build dragon-golems). This fits perfectly with my standard tactic, which is very well described in the "Teleport" spell.
I voted for Chaos as the weakest, although in reality, I think all 4 factions are quite well-balanced. Yes, this balance isn't immediately obvious, but it's not possible to say that anyone (even Haven!) is clearly weaker. Haven, for example, has very strong ranged units and very strong castle defense. I've always liked Blessings, and here, almost all of them are in Haven's magic.
