I'm sorry you don't play enough to see the imbalance. And that is exactly why there was a hotfix patch against OKW yesterday. GG
Though this patch contains absurd fuel prices, I can't tell it wasn't appropriate. Time will tell. So I have no biased attitude towards this verry issue.
You're telling an allies player to build side upgrades to "react" to Axis build. So as an Allies player I have to think about what an Axis player builds. But as OKW, it's okay just to blob volks? I just click panzershrek upgrade if I see vehicles? So much for foresight and adaptability.
So everything I mentioned are "side upgrades". Bazzokas, captain, ZIS, AT grenades. I see.
From where I am standing, this rather looks like refusal to adapt your playing style and BO in connection with what your opponent is doing. You just want to keep your build order and that's it.
Fine, but don't blame your loss against an X minutes pz 2 on OKW and on the "lack of balance" then.
