Heroes in Heroes of Might and Magic V: graphics, biographies, skills...

I agree with Katrin that specializing in monsters is not very effective, but only if there are few monsters in the slot. However, if there are many warriors in the slot, the attack and/or defense increase noticeably! The benefit is obvious! But I still agree with Katrin, and therefore I try to choose warriors with a specialization that increases their speed, as they tend to move slowly.
