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

Griffins are quite durable.

Are these weaklings really that durable?))) Only the combat griffins are durable; the others don't hold up well under attack.

Griffins are undoubtedly good, but they die quickly... And the AI loves to target them. Also, unimproved griffins aren't very useful, and improving them is very expensive.

That's exactly what I'm saying. Either upgrade them quickly, or don't build them at all.
