It kind of depends on the hitbox they give it and whether or not it has tracking. It works in risk of rain because the hitbox of the attack is quite large and enemies don't exactly move very fast. In destiny, we all know that it would have some crappy hitbox that would end up failing to function properly as current shoulder charge already fails to function on a regular basis due to the games shitty servers in pvp. Not to mention...this doesn't really fix what makes shoulder charge impractical for pve. It's still an ability where you have to ram through targets and chances are that unless they are dead, you are likely to bite the bullet because you put yourself in harm's way to deal damage. Something like shiverstrike or ballistic slam work because they offer a level of knockback as well as insubstantial end lag on animation. Shoulder charge MIGHT stagger an enemy but it's sluggishness to recover from the animation can get you killed.
