This, absolutely this! Really before a lot of the nerfing and class changing, nothing had really changed since year one. (Excluding both Alpha and Beta portion of the game) But it seems like whenever Bungie decides to introduce another weapon meta, the way people play using their abilities also changes quite a bit. Not entirely sure myself how shoulder Charge would help against the pulse, grasp thing going on. Maybe it's just a panic smash sort of thing when you round a corner?
