That same faction has a severe lack of medium tanks. This is why Relic needs to fix 4v4, I've never even seen a single Jagdtiger in 1v1 (ever!), but it seems like 4v4 is all about Wunderwaffen vs Armageddon Tanks.
As for the searching disparity, it's because of the Uniforms. Germans just look spiffier.
So the German uniforms is the cause of searching disparity? Sounds like NAZI friendship with Jewish people-AKA complete Joke.
The more people searching Aixs is because Aixs got more toys to play with, I don't remember the COH2 aixs uniform is cooler than the COH1, the searching disparity at that time were almost even.
