So after reading a bunch of comments here, these are the most common arguments that defend sprint. Here, I am not gonna explain why sprint sucks, I will simply counter the most common arguments. I wanted to post this as a separate post, but I'm not sure it's allowed considering this is the official sprint thread.
1. It speeds up the gameplay:
No, it doesn't. Gameplay is as fast as developers intend for it to be, and the average map size in Halo 4 is increased to accommodate sprint. It doesn't take any longer to traverse the average map in Halos 1, 2 or 3 than it does in Halo 4 or 5.
Also, with regard to the amount of time it takes to travel across maps in Halo, there is nothing that needs to be fixed. If you don't like taking the time to move across maps in Halo, to the point that you think a fundamental part of the way Halo plays needs to be changed just so you can travel a bit faster, then Halo might simply not be the game for you.
Inevitable response: "Um, no. I'm pretty sure that sprinting across Mercy is faster than walking across Mercy"
Ah, but you've already misunderstood the argument. The argument is not that sprinting across Haven is no faster than walking across Haven, the argument is that sprinting across the average map on Halo 4 is no faster than moving (at top speed) across the average map in Halo 1, 2 and 3 where the maps are smaller to accommodate a lack of sprint.
2. Halo feels slow without it:
Firstly, as pointed out above, if you don't like the way Halo feels without sprint, then Halo simply wasn't the game for you. Other people were absolutely fine with it, and not only were they fine with it, they actually appreciated it.
Secondly, the only reason you think Halo feels slow without sprint is because there is an illusion of speed that is created when running in bursts, even though you aren't necessarily getting anywhere faster. A person who sprints at 20 miles an hour from one side to the other in a 30-meter room will almost certainly feel like they're going faster than if they were to run at 10 miles an hour from one side to the other in a room that is half the size. There is no decrease in travel time, yet an illusion of speed is created because you are moving past your surroundings faster.
The human brain is more sensitive to immediate differences in speed than it is to differences in time that happen over longer periods; periods of time such as those experienced when traversing maps in Halo. Putting aside for a moment that it isn't actually necessary to make traversing maps faster in future titles, as that is not something that ever needed "fixing", I should mention that there is a much more appropriate way to increase the feeling of speed that you experience when moving around, and that is by doing any combination of these 4 things:
1) Decrease the average map size. This would mean less travel time, which is the effect that most sprint fans claim are a desirable impact of sprint on the game.
2) Increase base speed. This would mean less travel time AND it would mean that you were moving faster relative to your surroundings - one of the main reasons sprints gives an illusion of speed.
3) Increase field of view. An increased field of view gives the illusion of speed as it gives the impression that you are moving past your surroundings faster than if you had a lower field of view.
4) Through the use of vehicles, teleporters and man cannons on larger maps. By giving players more vehicles that are only effective for traveling, such as the Mongoose, you give them the means to travel across larger maps if they don't feel like traveling on foot.
Inevitable response: "but I can't shoot while I'm on a Mongoose. I want to be able to move and shoot at the same time!"
Isn't it funny then that you are arguing for sprint - a feature that completely takes away from your ability to shoot, melee and grenade while moving at top speed - by saying that vehicles aren't good enough because you can't shoot while using them?
Inevitable response: "but I can't stop and shoot right away if I'm in a Mongoose. I would have to stop and get out of it"
That's the trade-off that you experience when using vehicles. If you could simply drive a vehicle and then instantly get out and start shooting with only a slight delay, then you would not really be experiencing any drawbacks to using something that puts you at such an easy advantage. The Mongoose gets you across the maps in much less time than if you were simply to travel on foot, which means possibly (and likely) getting to advantageous spots/weapons/power-ups than those who didn't travel by vehicle. Not being able to shoot straight away after getting out is a tiny price to pay for having such a decrease in travel time.
3. I'm a super soldier in a sci-fi future - I should be able to sprint:
Firstly, as far as gameplay goes, gameplay is more important than canon. I mean, it sounds real obvious when I say it like that, but there are still many who use the 'I'm supposed to be a super soldier' argument.
Why are we not able to go prone? Why are we not able to aim down sights (yes, it would be possible even though there is a smart link system)?
Why are we not able to put our enemies in a rear naked choke? Why are we not able to cook grenades? Why are we not able to throw our knives? Why are we not able to kick? Why are we not able to wrestle?
There are any number of things that Spartans "should" be able to do as far as canon goes, but we can't do them as far as gameplay goes because many of them just simply wouldn't fit with what Halo is about. Sprint is no different.
If people were genuinely concerned about gameplay not completely reflecting canon, then they would all be complaining about all of the things that we can't do in-game, but they simply don't.
Secondly, if we were actually to go by canon, then we would be able to sprint at much faster speeds without having to stop after 5 seconds. Also, we would be able to do this while aiming and shooting accurately. The smart-link system doesn't simply shut down once a spartan decides to sprint, nor do a Spartans arms decide to suddenly lose the ability to raise.
For examples of Spartans sprinting and shooting, see Forward unto Dawn, Halo Legends: The Package, The Thursday War (Naomi), and any other examples that may I have forgotten.
4. Every game has sprint nowadays:
This doesn't come close to being a valid argument. There is no requirement that every game needs to be the same. Variety and uniqueness are far more valuable than monotony and lack of variety.
If you simply can't stand the idea of ever playing a game that doesn't include sprint, then the answer is simply to only play those games that do. It certainly doesn't mean that every game should sacrifice its own way of doing things simply so that you don't personally have to worry about there being games that don't cater 100% to your tastes.
Also, the 'every game has sprint these days' argument falls into two categories. One is the 'appeal to novelty', which is the false assertion that when something is new or modern, it is automatically good. This, of course, is untrue.
The other is the 'argument by consensus', which is the false assertion that when something is popular or common, therefore it is good. This, of course, is also untrue.
Whether or not every other game today has sprint has no bearing on whether or not sprint works for Halo. It is completely unrelated.
