i have used every aiming style on red dead. and the easiest one to use has to be casual. i know some consider it "cheating" but come on. the damn thing doesnt even target other players as easily. if anything it makes some game modes harder not easier.
another thing is glitches. speaking from the standpoint of a person who uses glitches a lot to complete challenges. i find them amusing. but sadly enough some people find glitches as a way to cheat. well that is why there are other sessions and private sessions to join. i think the people using these glitches should not use them to attack others. but rather just to have fun. why not kill officers or people in your own posse. i think people need to grow up. its only a game.
