Vampires. Discussion.

HOWEVER, in my opinion, in the fifth game, they are not worse (under certain conditions).

Worse, definitely worse. And it's not even about the stats (it's just a unit of a different level), they significantly reduced the life drain. Vampires are, of course, no worse than other level 4 units, but they are not better either, which is a pity. It all depends on the situation.
