That's indeed the whole point with panzershrecks. OKW has many specialized anti-infantry units and a crappy AT gun. The panzershreks were the glue that held the faction together and allowed for several different playstyles. I don't see how this was a bad thing.
All of the changes made in the past that led to more variety always improved the game. Nerfing of the call-in meta made a lot more commanders viable for all factions. Removing OKWs resource penalty opened up a lot more strategies for them. Removing shreks will do the opposite of that.
your last sentence is absolutely wrong. No faction among all 5 factions has the diversity of units OKW has and none of them can adopt to play various playstyles and strategies as OKW has. why one may thing OKW has problem without shreck? just compare it to OST! OKW has great infantry, Obers, falls, panzerfusiliers, JLIs, sturmpios, even without shreck, OKW still has the best Anti Tank options in the game. They have rocketen which has cammo, retreat and garrison options, they have the best light, medium, and heavy tank destroyer in the game (puma, jp4, JT). with panzerfuast granted to volks, they will have snare ability to volks, falls, and fussiliers.
not to mention the other benefits they have over other factions, most importantly their trucks, etc.
There is no way in the world OKW will have problem without shrecks with all their AT options, the players just need to adopt and instead of just relying on volks shreck blobs, try to use all the available AT options they have, i.e. invest fuel, mp etc on armor or rocketen, as OST does.
