The STG on volks really doesn't belong there. As @PencilBatRation mentioned before, giving volks an upgrade for 5x MP40s would be a much better option. It would practically turn them into assault grenadiers with better utility (or conscripts with the ppsh upgrade). This would give you a choice between being frontline infantry or an assault unit. The upgrade would give a much more noticeable difference and will require better reasoning to buy it.

People are crying because they don't find purpose to AssGren past 5 minutes and you want to give OKW a sort of after 5 minutes? Volks aren't assault section, you have the sturmpio for that.

I gotta say, anything the Ostwind can do the p4 can do. Ostwind might be a little better against blobs, but it will almost never wipe squads, like the p4 can with some rng. For just a little more fuel you can get out the p4 and also have it counter tanks. It is just not worth it to get the Ostwind as Ostheer. It's the same thing with the scott, you are better off saving your time and fuel waiting for the extra fuel for the sherman.

Ostwind deals massive damage in minimum time while Pz4 deals a bit more consistent damage in more time. With an Ostwind, you get in position, unload your firepower, move and reload, stop and unload, etc... With a stug around or a pak, this unit is a much more bigger threat than a Pz4 because you can't really kill it with your medium unless you are already in superior position.
Facing a blob, an HMG42 + Ostwind is just incomparable with a HMG42 and a Pz4.
Facing usual non-blobbing strategy, Ostwind is a defensive asset able to lock down a territory in a much reliable way than a Pz4.
the turret is moving faster, shot faster, better scatter, the unit itself isn't slower than a Pz4.
I don't really know what you want more. 1 Stug + 1 Ostwind is much less expensive than 2 Pz4 or 1 stug + 1 Pz4. they are just specialized unit that need a bit more of micro than Pz4 to be performing well.

As mainly USF player around rank 150 I prefer to see 1 or 2 Pz4 than Stug and Ostwind in front of me. Now maybe it changes a lot around rank 50.
I also think it is a question of preference, I understand the need for a generalist unit you can rely on to counter armor and infantry but when I play Ostheer I like more using specialized units

Ostwind is trash. Atleast with a p4 you can get some lucky wipes and beat back mediums, for only a little bit more fuel.

Ostwind is a beast when stationary = defensive asset, you're not using it the same way as a P4 which is best used offensively. Now I agree on the fact, it isn't the first tank you build in 1vs1 as much as a Scott isn't the first tank you build in 1vs1 as USF.

stug = counter medium tanks
Pz4 = counter light tanks (stuart/AEC/T70) with a good anti-infantry potential and then with vet can go toes to toes with mediums
It is really important to understand what you are building and what for.

Now, how to use a Pz4, like any other medium tank, with comprehension and not getting too greedy with it. Use it as an armored backbone support for a general offensive and not like a lone hunter that will get hit once by an AT and then naded and engine broken till its death.
you have MG42/Grenadiers/Mortar/Sniper to move with, taking advantageous positions on the middle of the map with its support. And when you do have consolidate your new position, move it around to kill flankers.

My personal playstyle does not include Pz4, I usually go for a 2 stugs because I'm counting on my skill to soft counter early light tanks (2x 222) while enforcing my AI power and then have stugs ready for the mediums.

1. so what am i going to do with 3/4 useless squads?

2. nothing to do with micro. the m10 nearly has twice the penetration and the aec does the same thing but much cheaper.

The puma is without a doubt the most cost ineffective unit in the game but you dont play okw so you do not know anyway.

Meatshield.

M10 comes much later, linked to a doctrine and is actually a tank destroyer. Puma is an light tank destroyer. Can't you see the difference? You are really hopeless in your way...

The limitation really just forced from one popular meta to making another, which I'm sure was the intention. That they didn't limit Churchills or KV-1s pretty much exemplifies this being flawed logic, but what the hell it changes the game lelic style, right?

All doctrinal units had clear differences in advantages compared to stock units, and almost all of them are either more expensive as compensation, or deliberately sucky but comes earlier and cheaper. Tigers compared to Panthers etc are no different.

If they ninja-changed the game so you could in fact call in unlimited heavies besides King Tiger and Tiger Ace, I'm 99% sure no one would ever notice...nor ever take advantage of it. And before you say "well what's the point then?" I cite their removal of duplicate bulletins: the point is just design decision, nothing more.

You loved so much the Tiger/IS2 stall meta to say that? limiting them by 1 was the best move taken about those units.
