Thing is the K/D ration in my eyes is just a campo meter,the higher it is ,shows how much people have camped.Anyone can get a good K/D when there playing the game mode that suites them and they camp for a kill streak reward,all you need is a 5 kill streak and you can hide for all the rest of the game and pray you pred-harrier-pavelow can pick some kills for ya.You don't even need to get involved in the game mode,say if its domination just sit back with a view of the domination flag and pick people off.The game was broken when they introduced the new kill streak rewards,they should have been at least double what they are 10 predator,14 harrier,18 pavelow infact if they just did that on hardcore modes would have been fine.
I have played with loads people with high K/D and all of them have never got involved with the game objectives,or there excuse is i am defending the flags,I have even done it myself ,when i went for the end game challenge which took me about 2 days to do with just camping with our group while they got flags i just sat over one and raped,and all it done was make me hate the game more,that's why i went and played hcsd.The people who brag about K/D to me means there only playing it knowing they need to keep there good K/D ratio so any opportunity they get they will camp
