I have to disagree with most of you guys. I'm playing the game a lot slower and thought out than this guy and thus scored many kills on that type of players. His opponents didn't have a clue and got caught guards down all the time.
Aside from that Apartments is a very compact map with a huge advantage for the germans before A and B are captured or in the transition from A/B to C/D with few remaining lonesome defenders in the first apartment complex.
Why does everybody belief, that the only way to play a game, has to be the one they prefer. Why should everybody be forced to play your style. You can be pretty successful playing both ways and I'm fine with it.
There's no doubt that an assault playing MP40, PPSH or MKB has a big advantage in this kind of CQC. It's tough to compete with a bolt rifle at that point. But it's hell of a lot fun to hipshoot or stab those guys. Not easy but satisfying.
Another thing to keep in mind: My goal is to stay alive and cap/defend territory not to kill as many foes as possible in front of their spawn. As a defender you can successfully create an area of denial by other means, than running around like a maniac on amphetamines. I' ll leave that to someone else.
