The weakest castle in Heroes of Might and Magic IV!

It's a pity that we don't have many Heroes 4 experts on our portal!
There are no inherently weak factions, some are just more convenient in certain situations than others.

That's true. Usually, in such topics, there are a lot of arguments. But about what? One, for example, is an expert at playing as Necromancers but doesn't know how to play as Sylvan. Another is an expert at playing as Sylvan but doesn't know how to play as Necropolis. Then someone declares themselves an expert in Chaos, but plays poorly as Sylvan and Necropolis, and they start arguing with each other, without finding a common solution. Everyone remains with their own opinion.
