They should have left the horses, the regular Maniac isn't bad, but the upgraded one is a complete mess. I haven't encountered such an uninteresting and simultaneously absurd unit anywhere else. What makes him scary? Enough whining about this already. After all, the artwork and the unit model in the game differ slightly, and on the battlefield, everything will look even smaller.
P.S. Soon, three games will merge into one: Heroes of Might and Magic, Arcomage, and King's Bounty 7 :D
