They removed everything that made halo 2 such a fun game (BXR, Quad Shot, 3 Shot, super jump) all those glitches in the game are what made it halo-2. Clearly there is no intention to make a halo 2 competitive scene as to my knowledge there is absolutely no ranking system "Yet" and the meaty portion of the multi-player is a combination of all four games over-layed on the halo 4 engine so what gives? What is it with developers ruining the fun parts in games nowadays, I'm willing to bet there are now invisible barriers in all of our favorite multi-player shortcuts and "trick jumps"
