Alright, want to be "real?" A lot of the changes that people have loved have been the same changes proposed by the very "vocal minority" since Halo 2. Sometimes the vocal minority knows what's best for the silent majority, don't you agree? Just because we are the vocal minority doesn't mean there is no hope, especially when it won't have any significant impact on sales because what number realistically won't buy Halo 5 if it has faster movement speed over sprint? If you can't quantify that, then your arguments and posts about not use arguing against sprint seem silly imo.
Of course I can't tell you how many people wouldn't buy it, but I can tell you that reviewers would start docking points for things like no sprint, no ADS, etc.
Metacritics matter to the devs, they don't give a shit about your perfect game, bud.
