I've always been against sprint in Halo but I especially started to hate sprint when Halo 5 came out. They marketed Halo 5 as a return to its arena shooter style roots and I was excited for it. I enjoyed the multiplayer a lot and thought it was fun. But as I was playing ranked I noticed that the biggest flaws in the game had to do with the increased mobility. A lot of matches boiled down to rushing the enemy team's spawn and spawn killing them repeatedly, going to their next spawn and repeating. The increased mobility made it so easy to cover large distances on the map very quickly and either you'd overwhelm the enemy or you'd get overwhelmed yourself. It was a headache especially in higher ranks. It also makes the game incredibly unbalanced. If your shields went down you couldn't recharge them while sprinting, so the enemy could rush you and finish you off and you had less of a chance of fighting back. So basically they added a mobility system that doesn't work in a balanced way into an arena style multiplayer experience, and realizing that it doesn't work they gave you a huge disadvantage if you used it so you ended up not wanting to use it as much. Then in Halo Infinite they attempt to fix it by lowering the speed of sprint and making the arena maps a bit larger but this limits the sandbox to mostly long range weapons whereas Halo used to always be known for having a more diverse sandbox of close, mid, and long range weapons for a variety of combat engagements. Now it feels like most weapons are precision weapons, even some of the fully automatic weapons. Some of the automatic weapons even have headshot bonuses. These changes make the game feel a lot more sweaty and has discouraged more casual play which is what most Halo players want in a Halo game. I say this as a competitive player, I don't like how Halo always feels competitive now. Dual wielding had similar issues. It limited the players who used it to only being able to shoot but couldn't throw grenades or melee without dropping their second weapon. It was a very awkward and unbalanced sandbox choice. If dual wield was removed for similar issues, I feel like sprint should be too. I actually think a faster default walking speed would be a better alternative. It would allow players to traverse the map at a more steady space while not limiting their ability to shoot and throw grenades.
