Again this scenario rewarded 800 prestige for MV. That is simply not enough for me to carry on and give useful feedback. I need at least 2-3k prestige awarded scenario playing with a fresh core on Manstein. That's fine, I shouldn't be able to win DV without an optimized core, and I'm satisfied with that. But the issue now becomes I probably won't have enough prestige to do much except squeak out a MV here and there, perhaps with some losses. From a gameplay perspective, I finally got what I wished for, and I may revisit this in the future. However, for testing purposes, this is not particularly informative, as reporting MV, losses on Manstein is what should be expected.

My kill/loss ratio is much better than history (although if you take step losses account, perhaps it's more like historical ratios). I believe the Germans, still at this point, generally inflicted at least 3-4 times as many casualties on the Soviets, and often more. I cannot really replace my losses, just like history too...
Balancing prestige is particularly hard. I actually think this quantity of prestige is fine as long as a player imports his core. All those heroes/prior experience will really help. On the one hand, you have to consider the starting core strength. On the other hand, you have to consider players who somehow have 40k prestige saved up by the start of DLC 43. It's probably best to err on the side of caution though, and limit prestige in general. I would not mind a small increase, but I would not like a massive buff to anything except the starting prestige.
I'm sure with a Manstein-optimized core I can win DV on these maps, they are challenging but not too hard. I like the general increase in difficulty though.
In conclusion: Do not change the difficulty! I am pleased that with the DLC 43 core on Manstein I cannot win this campaign, just like in history. If anyone wants a a historical flavor of what it was like in 1943, this is perfect. For now though, it's easy mode time for me.
