I'm having trouble dealing with Bang hopping back and forth over my head sticking out blocked crossup attempts. Barrier pushes him out, but not far enough - he can just keep going back and forth over my head if it's blocked, and I can't find a damn thing to do about it. 2C just doesn't have the hitbox to manage tagging him when he tries this, and if I wait for her to turn around then it's too late and I'm already getting kicked in the face. Help?
