I personally do but everyone has their own idea of a good player. For example I play TDM more than any gamemode. Who wins is decided by which team gets the most kills in the end. Now if I'm averaging at 4.70 kills to deaths then I very much believe that ratio does show who is the better player. I understand that for other game modes then it is easy to see kills to death as unimportant but if a player manages to get a good killstreak reward in the game and use it to their teams advantage (For example using the AC130 to blow up anybody who attempts to capture a point in domination) then that also makes them a very good and valuable player.
Just my opinion of course though.
Besides, it needs to be said that a high K/D is Usually the result of a better player due to a multitude of gameplay aspects, eg. Vision, Accuracy and reaction time.
Yeah, but you're gay
I'm too scared to play it at the moment, I bumped up the sensitivity to 10 and went from 2.84 to 2.72 K/D in a day.

Want it above 3.00 again.

Ah well, I'll play it again soon. Despite the message you sent me on PSN, I'm still looking forward to playing M.A.G with my housemates.
