With due respect, I don't think your avatar and ID fit in the post, as some people would get the first impression that this patch is going to be biased lol
That, in addition to doctrinal specifics, would have made OKW-Ostheer play more diverse in team games, but would have also kept the historical picture of less mobile German forces on defence against Allies on the move - something that made vCoH feel so sensible and historically accurate compared to this title.
But OKW was designed to be a highly offensive and early-game concentrated faction.
This is an overhaul, not a balance. David Kim might like this considering what he's been doing recently, but most players won't. I agree with 5% of your ideas.
Complaining penal terminators, stormPGs, 0 tech Pak40, base sector halftruck and so on is an endless thing, but the core issue here is this overhaul is trying to use asymmetrically designed game elements to make a symmetric game, this is not very likely to work out and the result won't be very appealing to this game's original users.
Yeah replacing the mortar with WC51 could be better since seems an early game MG counter is all that USF needs, according to Relic. I'm sure those GI will appreciate the change too.
