It is not only the OKW problem. Both Western front Armies need to pick a doctrine to fully counter MGs in buildings for example Armor Company for Assault Engieners.
It is simple OKW needs an anti Blob and anti Spam unit, because allies only spam and blob. Allies dont need anti blob units,because Axis never spam and never blob they only and always use combined arms right?
In my last 3vs3 on Steppes my OKW opponents blobed with 4 sturmpioners, 4 volks, 2 obers all three of them. We didnt blob or had HMGS with AA halftrack so we lost. The Pack Howi did good but not good enough and the thing that hurt the most we ran into their base wiped nearly all their squads but they returned together with a new blob and many panthers. We lost to blob tactics and that hurts.
Well the Tiger Ace is a doctrinal unit, so not everybody has it. It is fine as it is and please stop calling for Axis nerfs everywhere i do play mostly USF and i do have trouble with Axis let's call it design, but not all units needs to be nerfed to the ground to call it "balanced". And like Van Vort said this games needs also other solutions to problems not simple A move to win or slugfest tactics.
