Which faction do you like the most in Heroes of Might and Magic IV?

What did they do with life? They just buffed the Crusaders and that’s it.

Well, not exactly. If you want, I’ll try to find all the changes that increase Life, and in my opinion, these are the most significant changes in version 4, rather than changes affecting other factions.
P.S. It’s a pity that there are changes that weakened Chaos.
