Why, obviously, yes! Humans are fully capable of traveling at 6 - 9 mph when sprinting, whereas walking can only move their bodies at 2 - 4 mph. Just like in real life, when you are sprinting, you were genetically allowed to sprint to escape danger and predators. Adrenaline locks your muscles into the groove, and your only focus is R-U-N! You have no time to deal with such petty things as ‘aiming your weapon’, or ‘throwing a grenade’. This view on the human agility is realistic, therefore, to want sprint to stay in Halo 5: Guardians is an objective reasoning.
When I play Halo, I want to ‘run-and-gun’. When I play Call of Duty, I don’t want to, but I ‘creep-and-crawl’. What made Halo so good with out-in-the-open combat was that you had lots of health and your walk cycle was fast. “All of the “good” Halo’s didn’t bother with sprint, so why should Halo 5: Guardians”? This is subjective reasoning.
Normally, I would choose one of the two, but there is always the third party: Indifference. Why not handicap / nerf / buff / spike / fix / tweak / change / penalize / sugarcoat / consequence the mechanics and balance of sprinting, so that ‘cat-and-mouse’ chases are null and players are encouraged to move faster?
Me, personally, I am indifferently AND/OR objectively rational. If indifference can’t win, objective will.
