Besides perhaps Scavenge, I don't really see what other OKW commanders would need. OKW has the biggest set of viable commanders in the game imo. Apart from Scavenge (that is getting 2 buffs already) and Fortifications (1 big buff and some small ones) all commanders are popular across the different modes.
The goal of this patch is not to create more top tier commanders, it's to bring as many commanders to the middle tier as possible. And the majority of OKW commanders is already at that middle tier.
I don't see how those commanders are any good
How frequent the 221 is in those games, the 15 fuel car that comes after 15 fuel of tech and can barely go toe to toe with unupgraded UC? How well does Panzer Commander synergize with a commander that has an heavy that doesn't use it (meaning you will have at best another panzer 4 with it, and surely not a panther ehich benefits the most from it)?
How reliable is the Sturmtiger, especially compared to the avre?
