Raketenwerfer 43 is situational and wont work well on all maps, especially not against a skilled USF player that have shermans + big blob of M1919 LMGs or flamers.
Raketenwerfer 43 dont have the same AT + AI mobility as Panzerschreck volks and also has less durability than other AT guns. Using Raketenwerfer aggressively similar to pak40 + suppport against USF without faust nor Werh's long range target weak point is very risky. Playing OKW without Panzerschreck feel like playing a WW1 game (to defensive). Using a Panther against M36s are also very risky now due to less mobility, less durability (easier to kite with M36/M10), no smoke and bad options to clear M20 mines. It's also much safer trying to flank M36/M10s with Panzerschreck rather than AT guns. So without alot of Panzerschrecks that Panther will have to be used defensive as well.
The problem with OKWs mid game now is that they have poor flexiblity and mobility without alot of munitions. OKW dont have medium AI/AT tanks so they rely on infantry support to carry their mid game armor.
OKW still dont have any good non-fuel counter arty (the stuka which are risky to get early in 1vs1), so playing OKW defensively mid game are not really viable against a skilled opponent that are abusing OKWs lack of counter arty options.
One of the best way to fix OKWs mid game are to buff fuel to munitions conversion from the truck so they can play similar to the Werh close air support commander.
Most players dont have the Jesulin micro to use flak ht effectively against cons spam let alone ptrs. Make one mistake with the flak ht and it can be killed pretty easily. Panther + Ostwind + infiltration grenades as counter imo which has the durability allowing a few mistakes. When stationary the panther MG upgrade are pretty good at killing cons and get the panther to vet2 asap.
T70 supported by shocks is a beast against OKW now. Kiting volks shreaks with T70 is easier due to long range accuracy nerf. Cons with at grenades are also good now because OKW need puma to shut down the T70/shocks combo or OKW will lose to much map control.
Mgs + cons are still viable on maps where its hard to flank with con spam but only if supported by early T70/T76 + maybe a zis gun to counter flak ht. Cons provide good AT defence against puma so OKW dont need zis guns until panther or flak ht. The primary reason why mgs are viable are because it can bait OKW into spending munitions for grenades which they really need for obers/shreaks or they might go infiltration grenades = no pak43.
If OKW dont get early obers/falls then shocks will rape volks. If they get early obers then they have less shreaks to counter early T70. OKW still got a strong late game but it takes longer to get going because obers cost munitions. If soviet + USF focus to starve axis from munitions they can usually win the early+mid game. Imo allies early/mid game are pretty OP now in 1vs1 but 2vs2 are pretty balanced.
OKW was only OP in team games, 1vs1 not so much. Now when I play soviet OKW feel much weaker than werh. OKW still have a strong late game but their early-mid game is to weak now that they dont have the saving grace of OP obers. The patch was fine and obers needed a nerf but OKW early/mid game still need some fine-tuning.
My suggestion;
1) Sturmpioneers flamer upgrade which OKW cant spam anyway so 1-2 SP with flamers should be fine.
2) For its price tag which are similar to 120mm mortars the LEIG infantry support gun still sucks and it dont scale well due to strange veterancy bonuses. Vet bonus instead should give them more armor penetration so mid game they can supplement OKWs lack of counters to sherman spam. AT guns and tank destroyers (Puma/Jagdpanzer IV) wont work on non-open maps so OKW need someething else in the mid game until they can get a panther out.
I had a tough early game but with shocks+KV8 I was able to prevent OKW from getting map control. ihitto have won most games in the past but this one was pretty close.
