1. Even if the barrage was improved, it'd still generally be only ideal vs stationary/slow targets like weapon teams and OKW trucks and USF still lacks any real non-doctrinal indirect fire which the Major could fill. If we gave it a long cooldown that got better as he vetted, easy given how officers get shared xp, he'd be the USF's unique take on artillery. Also would mean the Major would be seen closer to the front and be more than a glorified retreat point. Do you want artillery for an assault or a retreat point? Range adjustments might be needed.
And any artillery is generally bad news for OKW trucks or British emplacements, but that's why you bump up the cooldown to give pios time to repair if it was free.
2. I guess that's another way of doing it, though I dislike how even at max range that the leig and pack howitzer can land shots right into the lap of opposing infantry and weapon teams.
3. Guess it could be too good. Might as well go back to finding why for the timed AP shells to be better unless it just becomes a ZiS 3 when using AP ammo.
Not if the barrage gets to land a lot faster (A factor I had in mind for "effectiveness")! Following your concept though, an option would be the barrage getting cheaper from vet to aid more usage as well. I still think the barrage now, as is, has a performance completely uninteresting (free but bad non-doctrinal indirect fire is still you know,
bad indirect fire) that I'd rather see that bumped up even just a bit and then whatever else needs to be done to make the Major more than a glorified retreat point can still be done.
Well, the higher cost of those things still make them deserve some sort distinct advantage over mortars. Definitely could still use tweaks, but I'd think it'd be definitely strange for these higher cost indirects to be generally less threatening to static units than a simple mortar's saturation of rounds so I'd prefer the accuracy at least mostly stay.
Well, I still think the concept is worth considering, since AP shells for the 57mm don't have all that much decision-making right now anyway (if tank, then AP shells. Hope you have munitions. Don't get flanked!). I'm just trying to lay out what I figure the numbers would be if your words were followed pretty exactly. Nerfing the 57mm's vet 1 would definitely be necessary were it given the ability to have at least average pen at all times though, if we don't just increase the thing's price.
