>But what does that faster walking speed actually help you do?
get into better position for your character skill, move into engage priority targets while clicking your contested health back, you absolutely can pop spore mines or stagger or headshot gaunts that are going to melee you. if you are dodging devourers or chaos marine shots, more movement is better since they calculate your velocity and where you will be but if you are far enough away walking while aiming is fine. the only classes that wouldnt benefit much is tact and sniper, heavy would still find use if you are using your halo proactivly, although even tact can make use of mobility to utilize his aoe execute damage.

with the bolt pistol its often better to click and hit 4/6 shots while moving than it is to stand there and hit 3/4 shots in the same amount of time, especially if you are putting a majoris into execute while positioning or killing ranged minoris
