Playing Vampire Counts lately, I realized that the zombie and skeleton summons I was raising got literally no benefits from all the skill points and technology I was investing into making normal zombies and skeletons better. Even the special regeneration ability the zombies are all supposed to get from Kemmler's unique equipment was not applying. Just take a look at the difference:
For the record the rank 4 chevron is only giving +4 leadership and +1 Melee Attack/Defense.
I think the most frustrating part of all this is that without getting any of the bonuses I've picked up, summoned unit's leadership is often absolutely abysmal. You can see on the unit card, that the only thing keeping my recruited zombies in the fight are the +leadership bonuses I've picked up. It's all well and good that zombies are meant to just be sacrificial meat shields, but it's kind of hard to fulfill that role when their summoned version begins crumbling the second I spawn them. I also see similar things happening with Menace Below vs anything that isn't an archer.
Summoned units should get all the factionwide and Lord Buffs that apply to their non-summoned counterpart. This would not only help future-proof them into the mid-late game, but would give value to picking up skills/techs for units you might not get otherwise. It's also intuitive that summoned clan rats or zombies would benefit from technology that buffs clan rats or zombies.
