The reason no one wants sprint is that none of the classic Halo experiences would have benefited from sprint. From 2v2 battles on Chill Out to 8v8 on Sandtrap. When you add in a mechanic like Sprint you fundamentally change the way the game plays, and have to change the design of maps to accommodate this, in a way that moves from what Halo has represented to something entirely different.
The problem for me seeing ADS even if just visually combined with the inclusion again in sprint, is it shows the thinking in 343 doesn't seem to have changed. The same type of thinking which led to the biggest and quickest drop in Xbox Live users for a Halo game ever in Halo 4. There again taking ques from other shooters, rather than making sure Halo stands on its own. That it represents something else, another class of shooter, rather than becoming synonymous with generic modern FPS ("tick box" based game design). I hope to be proven completely wrong by their reveal, but its not a good sign at all.
I just want to clarify I don't think there's anything wrong with Sprint/ADS etc if your into it, and if 343 wants to make a game like that fair enough, but their insistence to add it to Halo will always be an issue. Halo has its own style of gaming, your not being 'innovative' breaking the DNA of Halo, your just taking the piss out of fans who like the type of gaming Halo represents, and hearing reasons as to why taking features which we all know originated from other games and making them "work" in Halo is never going to be properly justified or accepted.
Make another game and call it what you want, add in these features and let your game stand on its own.
