There's nothing wrong with shoulder charge. It can be countered by nearly anything: any special weapon, grenades, Wombo combo, supers, warlock solar shields, and most meta weapons. Trip mine can leave you one shot, yet people want it buffed (I have no problem with that except that they also want lightning to be nerfed). Most warlock grenades such as storm grenade, or solar grenade can leave you one shot upon impact. The dreaded skip grenade can out right kill you under the right conditions, and unlike lightning, which is stationary can track you.
