Not sure about that. I play rumble, because I experience the same frustration as you and many others. Your chances of winning team games, while playing alone is not as high as it should be. More often than not, your team can't hold their own. For that reason, I play in rumble. I have found a large chunk of my opponents are not that great. I think I'm an above average player, but my K/D in rumble is a lot higher than any other playlist. I come across the odd guy that's good and he'll give me a close game. Probably one every few games.
