Honestly the only 2 reason I still play Ostheer and not OKW in my AT 2vs2 are: Sniper and spotting scope.
Consider if we goes double OKW and we meet high - skilled Allies sniper play then we are truly fucked. It's painful for me to use Ostheer with their 4 man squads can getting rekt so fast against AoE weapon because they only have 4 man...
Jaegers are a good OKW counter to snipers, and with overwatch you also get lefh for the late game
