There was enough to be hopeful, but sprint ruined the Halo franchise. They should have just up'd the default speed and ditched it. Or they need to take what Apex did and offer auto-run as a menu option. That was the biggest complaint for the first 6 months of Apex's release. I don't know of a single player that has this turned off in Apex and is worth a shit, so normal walk speed may as well not exist (99.9% of the time its either run or crouch). Just because other games did it doesn't mean it has any business being in Halo.
Valorant did the same thing. Good players immediately set run to default and only slow down via button, when necessary.
I somehow doubt 343 is going to get this right.
