Strikers are designed as a cqc class. They have no abilities buffing gunplay, no abilities improving overall effectiveness at gun fights or grenades that are helpful in straight up gun fights. They are designed to fight as such, and the fact that they can be countered in so many different ways proves exactly my point, that it isn't op. Every op gun so far in the game has only been able to be countered by the same weapon. Doctrine could only be countered by doctrine and Arminius. Snipers could only be countered by snipers. Thorn could only be countered by tlw and thorn. Get the gist? With this in mind you can see very well that shoulder charge can't be overpowered because it can be countered by every weapon in the game.
