Which monster do you like the most in Heroes 5 (level 4)?

Crazy, it's not that easy to target 4 units at once. They might be useful for clearing out creeps, but in the final stages, they become suicide units that consistently eliminate 1 unit due to their armor penetration. If the enemy doesn't destroy them before their next turn, their chances will be significantly reduced. Therefore, they are effective as suicide units. Vampires, on the other hand, last longer on the battlefield, but their damage per attack is significantly lower. Overall effectiveness during a battle cannot be definitively assessed; it all depends on various circumstances. Comparing which is better, a vampire or a lizardman, is a pointless and silly exercise.
