You mention that someone who plays correctly with that ability is very hard to counter, and I could say the same about people using shade step and using it almost every chance they get. But that doesn't make it overpowered, that is people using what they have on their subclass, combined with good spatial awareness and mobility. After having seen your load out, which always has at least 1 close range weapon (last word, hand cannon, or shotgun) I am very unsure if shoulder charge is really the problem. I don't mean to sound rude, but if somebody is rushing at you without a gun, even one with good spatial awareness and mobility as you say, and you are unable to kill them, it might be your aim. Of course, they might get you some of the time, but with a close range weapon such as the ones you have you should be able to kill targets that close to you who are not firing at you. Now, onto the tracking and aim assist. You say that it curves, and it has to for it to be usable because it would be too easy to avoid if it didn't track targets who were moving (which causes you to curve mid shoulder charge). Also, if you are getting shoulder charged around corners when they are not looking at you, what is happening is the person is moving past the door, spinning their camera towards you and shoulder charging in that direction before the character in game spins in that direction. Also, you mention that it is a free one hit kill with health recovery, but backstab with the right build does exactly that. Granted, it is easier to be able to do this from the front, even without a gun, than to do it from the back with a gun while standing. But I also think that you made it seem like all you have to do is run and boom there is a kill, and given what I talked about with being able to counter with close range weapons and spatial awareness, it seems somewhat unjustified.
