Gearheads of War

I know the connection speed for the game host is important, But would a faster connection speed help a player who is not hosting a match. I was told that your connection speed will move in waves with various high and low points. Do these High and Low points change the playability in a MP match. Macaface asked the question on consistency and I also am a player who sometimes is all over the place, even when teams have not changed and the matches are on a cycle. How do the rounds coming out of my weapons vary so much from match to match? I am not playing any different then I was last match. So is there something in the connection speed which drags you down and later raises you up a notch?
My conection right now is 1.5 Mbps, my provider offers up too 10 Mbps starting march first.
Would increasing my connection speed make my muti-player expierence more level and cosisitent?
If any one has any answers it would be great.
