Another thing confusing me is that in previous games I've never felt that the Dexterity equivalent helped at all, so I never used it. Yet in this game I feel like it helps me significantly.
It had much better perk competition in the older games. In BO1, you were better off with SoH Pro. In MW2, it was Lightweight Pro, which was competing with Stopping Power and Cold Blooded (I had an SnD class with it though).
Besides, now with half of its competition literally useless, and the fact that you can double up Dex with Engi or Tac Mask, its pretty much standard-issue for aggressive play. And you climb like Snorlax in this game, so it helps there.
I'm trying to get my SPM up to 400, so sprinting everywhere is my best option.

Dexterity doesnt do much for ARs.. cuts time by like 35%.. smgs 50%.. lmgs.. its cuts above 50%.. but running around with a lmg.. your going to set up your class right to be effective.. in other words use it for smgs mostly.. lmgs if you fast mag.. lightwieight and other speed perks.. also target finder on lmgs.......
