New units in Necropolis. Discussion and selection between upgrades.

I think the alternate upgrade for liches seems rather useless. They are, of course, stronger than our other units, but an upgraded lich without the cloud, in my opinion, is not very effective. As for vampires, everything is clear here. The previous upgrade is more pleasing to the eye and more useful in battle. I won't repeat what I said before. Skeletons - both upgrades are equally good. Zombies - approximately the same, but I prefer the first one. Dragons - the same, but I prefer the second one. Ghosts - it depends on the situation. Here you need to know who you are playing against (see the abilities of the upgrades). Overall, it's a good idea, and I don't have any major complaints about the upgrades. But at the same time, the faction has definitely been weakened, but that's a different topic. I apologize for the typo; I have already corrected it.
