Since going to rank 4 in 2V2 as Axis I have played loads of different people.
The skill difference between a top 20 USF/Soviet player and a Brit player is INSANE. I have played top 10 brit players who are literally trash and rank 1000 with other factions. They are high with brit simply due to cancer doctrine. It's broken.
If you replaced "USF/Soviet player" with "Ostheer player", "a Brit player" with "an OKW player" and "top 10 brit players" with "top 10 OKW players" the specific statement would still be correct.
Advanced Emplacement Regiment might be broken in 2vs2 (and above of course) but double OKW is definitely either. We reached rank 1 without any effort (only fighting versus the discussed commander was challenging) and are already rank 2 because another double OKW team replaced us - how ironic!
Speaking of double OKW: I see you and your partner have also reached high ranks due to double OKW - how ironic.
