Struggling

Been a while, but I'm still about the same rank. I'm a 31 and all the higher I have been is a 33, which was very short lived. Over the last 224 games I have played in MLG game type since 8/11/2008 I am 99-125, which is far from stellar. However, I do feel as though I am playing very well. However, I think whenever you are playing this level of Halo it's very important to be playing with some teammates that communicate and are able to play well together. I never have that. At the very best it's me and Colby and although we play great together, a lot of times our teammates don't play that well. Anyhow today I went 2-3, but every game I was positive, 4 were objective games where I went 2-2 and the final game was TS on Guardian where I was +5, but all my teammates went negative. So hopefully I can start to team up with some people online and start consistently winning some games...
