Ah, I didn't know that (never queue dodged). Still, I don't understand that mentality. So what if you don't get in the same match? Seems like a waste of time. Same with dropping when a match is almost over. You still get some coms, cash, etc from a loss. "OMG! My W/L ratio will be screwed. What will everyone on the CoD message boards think?!?"
My guess would be that they just want easy ranked comms and perhaps to manipulate their ratings. There's always the possibility they just want to practisr. It could even be they fear the butt hurt and just want to jerk off their fragile egos.
And yes, people care more about numbers than the challenge of working for a win. Also, there are quite a lot of lazy people these days.
