There are different opinions due to different answers. CBR across all game modes probably indicates your playstyle is what the development team want. Kd in any mode can be inaccurate due to crossfire and lag. In the old days it was the high score table that counted. DT provides an average game score but different game modes offer different structures. Fun is the winner, yet again different players find fun in different ways. Most will usually find fun in self improvement in games. I have 1 friend that in battlefield didn't care about his kd, he just enjoyed blowing up tanks. For me, I have no interest in society so I don't care what others say. I find fun in a team, that doesn't mean tactics have to be used. Just have a laugh ;)
