It's always been that way, the halo community has always been the hardest to please. There were people complaining about halo 3's introduction of equipment, then reach's armor abilities, now halo 4's ranking systems, and each time the solution was to go back to the previous game. I personally like all of the halo games, because the creators do somthing the COD devs don't. THEY MAKE IT A DIFFERENT GAME. Your strategies in halo 3 will not work in reach, nor halo 4, and I doubt it in halo 5 or 6.
