Have you tried running an extended line test? Give that a go and see if it uncovers some instability in your connection. The only other thing that springs to mind is changing your DNS to that of Googles. I dont know how it helps, but a friend of mine who is a networking whiz suggested it in a megathread he made about connection optimization on the CoD forums way back when. As for whether its fair etc... its either you, or the other 7 to 11 players who suffer. Its not hard to see which way Bungie will sway on that. Its also perfectly possible to lag balls without actually realising it. Its happened to me a few times - once due to "Traffic Management" from my ISP, other times my router shat the bed and needed to be powercycled.
