I know this is a satire. But I occasionally still PvP with my Titan (my Lock is my PvP main now) and I find shoulder charge easily countered by shotguns. Simply put, you pop up on a radar as an incoming target and most people will switch to their shotguns immediately and blast you as you fly by whiffing them altogether. I am spec'd for it though because I find it as a maneuvering tool extremely effective.
