I'm with Seph on this one. It's more subtle than Halo 4's implementation, but there's some "innovative retro-bandaiding" going on with the game design right now. With Halo 4 it was more critically toxic to the gameplay, where you'd have elements like "all players do not have Red Xs unless using the proper [Nemesis] perk" or "you're plainly obvious in Promethean Vision unless you use Wetwork," and so on and so forth. Halo 5's basically doing it with the Spartan Abilities, where map movement feels very "you've got one of the slowest movement speeds in a Halo title to date unless you're making use of Sprint or associated Spartan Abilities." It should really be something to the effect of "you've got a very high movement speed, and this can be further improved, not substituted, by Spartan Abilities."
I feel like whatever movement speed you have while wielding the Bane is nearly perfect. Just up everyone's speed to that and scrap Sprint.
