Replace stuka zu fuss with the mortar halftruck and add stuka to doctrine.
Its Vipper idea and the best on this forum.
A mortar halftrack in OKW's mechanized would probably be overpowered as hell.
As for the Opel Blitz, it's pretty worthless, and I'd rather see it replaced by the Ostheer Opel Blitz that can lock down sectors, to give OKW another doctrine that can secure some extra resources.
OKW needs Obers in tier 4 to counter the inevitable flood of Allied infantry mid-late game, when early units like the Flak HT, Luchs, Volks and HMG 34s are no longer adequate. It would hurt them if their only good late game AI is behind one of the techs that is usually skipped. A P4 is easily countered by a pair of ATG (talking team games here).
Mortar HT is also a dangerous idea, because OKW is a very mobile army with fausts everywhere and a mortar HT would be nearly impossible to counter. It would probably synergise too well. A Puma protecting the mortar HTs from early vehicle dives with Volks and HMG holding off the infantry would make them untouchable.
DPS numbers are originally all wrong because it's only counting the reload value without looking at fire aim, ready aim, wind up and wind down.
Either way DPS is a meaningless stat to take for a raw comparison. It doesn't tell us anything because there are a great many other factors that contribute to the offensive power itself (penetration, accuracy, turret y/n, abilities, alpha damage) and to the overal effectiveness of the vehicle.
Vipper has come closest to providing a meaningful comparison, taking penetration and accuracy into account and comparing them for a single range against a single target. But even this comparison is flawed on its own (because it inevitably misses a lot of other stuff) and can only be used as an indication, not as a full fledged argument.
Lowered penetration could make it really annoying to use too though. If one really wanted to make it less lethal I think a firerate reduction or even (mayyyyyybeee) damage reduction.
One historical way to make it unique is to give it the same (high) penetration at all ranges, but reduce damage to 120 or 100. Since it fires HEAT rockets.
Stock panther is there to deal with hard targets designed specifically not to be as vulnerable as mediums.
If the allies want a high armouered unit they need to select a doctrine specifically for it-brits aside. And again, the okw have specialized AT vehicles. The panther is there specifically for hard allied targets, like the JP4 excels against mediums and TDs. Listing off all the axis units with high armour, regardless of intent behind it isnt going to change the intended role of the su76 while the su85 sits with its over buffed pen itching for hard axis targets.
The is-2 remains the only heavy tank that will really give the axis a hard time and the JP4 will have an easier time getting through even allied purpose built heavy tanks that the old su85 would through axis stock units
Jesus, I know what the intended role of the Jagdpanzer IV is. That was not my point at all. I literally mentioned that in my post above yours. My point was nothing more than showing that the Allies do have quite a large number of high armor targets, after SupremeStefan claimed that the IS-2 was supposedly the only high armor unit.
And JP4 is not the unit intended to engage high armored units. Its why Panther exists.
What's your point?
If you had bothered to read into the context to which I was replying, you'd know that it was exactly my point that there are a lot of high armored units that the Jagdpanzer IV can't effectively engage. I never said that it should be able to. I was simply disproving SupremeStefan's claim that the IS-2 is the only high armor unit (compared to the Jagdpanzer IV's penetration values) on the Allied roster and nothing more.
