New units in Necropolis. Discussion and selection between upgrades.

This topic isn't a duplicate... Because here we discuss the differences and the principle of choosing one of the upgrades. And in that thread, it would be off-topic because it should only discuss the alt-upgrade... I have the same heroes as you... I'm currently playing the campaign... The vampire alt-upgrade is great... It applies stun after 3 attacks (1k7 is nonsense, that can't happen), and it's also a great blocker against ranged units (NEUTRAL), so I wouldn't put them in the front against another player... If I really want to, I'll pair them with specters... They reduce defense... The vampires take them down.
