Except the striker super has much less tracking, the shoulder charge has limited vertical tracking, meaning that dodging it is as easy as jumping and staying high above the titan, you have to get kills to keep the duration up, and there is no method to reduce the rate of super drain and you are perfectly visible the whole time. Shoulder charging is also the only reliable attack as well, since it is nearly as cheap as a spectral blades swipe, and using the slam costs a large chunk of your super that is slow, avoidable, and can't one shot supers. Bottom tree striker is quite balanced considering how mundane it's other perks in the tree are. It's better in PvE if anything.
