Adapt. That's what many people don't do. I expect to get shoulder charged 1-2 times a match. Now in inferno the radar is gone so that can go up a bit. Last inferno match I played a Titan kept running universal remote and sniper. He got me 3 times before I swapped from AR and fusion rifle to mida and shotgun. I figured out his run pattern on frontier. I got to a blind spot and he would run and try to charge but it was too soon to build up the SC so I filled him with buckshot. I did that 3 times. He caught on and I moved back to use sniper rifle. I figured his new pattern and hard scoped on his lane. I got him two more times. End of the match he had 20 kills with half from SC I got 16 with a third on him. We won but he left the next match.
