I think that shoulder charging out of a slide is ridiculous. Also in mid air. To shoulder charge you have to be running, not floating or sliding. It just doesn't make any sense and shouldn't be in the game.
Edit1: It's not the midair SC that bothers me as much as it is the slide

To pull this off you literally have a fraction of a second to do it, it can be very very hard and most of the time youll die anyway because of how many frames it takes to preform. When the rare chance it does happen its usually by a panicked low health 1shot titan who just got lucky
