The cycle only repeats like that if you play without thinking. Sprint is a tool just like every other ability and weapon you have. The reason this discussion keeps coming up is because not everyone agrees that sprint negatively impacting Halo is an inherent thing. I've seen a the discussions and still think sprint can work as a good addition to Halo.
Nah, it comes up because it's entrenched in the genre now, and so you have a minority who want to include it in Halo without taking into account most of the viewpoints/info against how it's detrimental to Halo, specifically, game play. Just like ADS.
I don't know why everyone feels the shooter genre is the one that needs to be homogenized. Everyone wants every game to have the same things in every other game. "I need 32v32 in Halo because I like it in Battlefield" etc.
But what do I know. I'm increasingly thinking 343 should just say fuck it, completely make a sprint, ADS, insta-kill melee, load outs, perks, Halo game, rake in the initial sales and move on. They'll probably still make a profit. The type of Halo game play I like is now relegated to niche status. So more power to them, and to others. Maybe Reach and Halo 4 weren't enough, maybe another go around is what's needed.
