The 17 pounder can be directly compared to the pak43 for the most part. They're both stationary AT guns with good range and a lot of firepower. It's not right to compare them in a vacuum, though, as they both have different enemies with different units supporting them.
We all know the drill. PaK43 is doctrinal and can shoot through walls, 17lber can brace etc, i won't waste time listing their traits.
I think we can all agree though the 17lber is virtually non-existent due to an outrageous 20 pop cap. I know there's a lot of hate for advanced emplacement doctrine, so a lot of people will immediately shit on any idea that buffs an emplacement out of spite. That is the wrong attitude.
I would also add that the Pak, like all other on-map non-UKF emplacements, is too vulnerable to being 1 shotted by offmap arty. The howitzers/guns should have enough hp to withstand the cheaper offmaps, excluding big things like air superiority
I think it should be no more than 14 pop and no less than 12.
