My official opinion? N/A, never played the game, probably won't either, so I honestly don't care one way or the other.
However, my sympathies to the people this affects. I mean, hey, you worked for whatever it is you got that they're screwing up, so bloody hell raise some, well, hell. An exclusive avi isn't enough in my opinion to lose your rank (unless that avi is your old rank)
Now, the personal stuff? Ugh... Halo... ~shudders~ Dun like the game, too many fanatics out there. If it wasn't such a hit and people weren't so, well... Zealot-like in their defense of the series or obsessed with claiming any FPS I personally like is inferior to it, I'd probably be willing to give it a shot. Not saying everyone's that way, but still, I've had enough run-in's with the fanatics -_-
