New units in Necropolis. Discussion and selection between upgrades.

There’s no need to start making accusations. I’m not trying to provoke anyone; I’m just sharing my experience, so please be respectful!
Let’s be reasonable; diverting two valuable units to engage a single stack isn’t very efficient. I prefer a tactic of attacking with 7th-level vampires and archers. The vampires should be able to operate independently. That’s their strength. As for ghosts, it’s better to use them against spellcasting units, so they can drain mana and resurrect themselves.
