Easily the most problematic thing I've found in the game thus far is the mechanical synergy between, or perhaps the lack thereof, the processes of both sprinting and reloading.
Though not entirely realistic, I reckon it has the capacity to bring an increased sense of fluidity to Destiny 2's current game-play.

This is why I really like 2 primaries I used to even reload Bad Juju while trying to run even though it already gave me all but one shot back, but now I can just switch to another weapon that can even be the same kind and keep firing, favorite loadout is the whatever devil gun and the sunshot if I can get in close to hip fire
