New units in Necropolis. Discussion and selection between upgrades.

1) Both skeletons are good. But I take archers at the beginning because I can't do without them, and over time their damage becomes almost negligible, so I gradually replace them with warriors. 2) Zombies. I always take the 1st upgrade. The weakening strike provides some benefit, and the damage is greater. But in general, they are both extremely useless. 3) I have never used the ability of the new upgrade. I don't even know how it is visually animated and when it can be used at all. The ability of the old upgrade triggered very rarely; by the time you reach the mage, he has already spent all his mana. Either he must have a lot of mana (more than for 2 turns), or he must not have any attacking spells that he always uses. Therefore, I don't consider this ability. And since the new ghost has better stats, I take the new one. 4) Vampires. I always take the first ones because nothing can replace retaliation!!! 5) Liches. I usually take both in equal numbers. But at the beginning, the new ones are more useful due to the resurrection ability. 6) Harbingers, because they are stronger in all parameters, despite the fact that the banshee has more health and a more useful ability. In the early stages, you kill strong units one by one, and against a hero with light, you use this ability to remove good spells from the enemy. Although banshees with their ability, along with the new dragons and the banshee's cry, would also look good with the hero. 7) Always the new dragons. -4 to morale and luck is a lot. Even if morale doesn't affect the enemy, their attacks will almost always be unsuccessful => half damage, which is much more useful than the weakening of the first dragons
