I laughed so hard. I had to check if this was a joke. An auto rifle is the go to if your aim is off. Hand cannons rewards someone with good aim. But I find them harder to use because setting up headshots takes more time to me. One important thing to keep in mind is your cross hair placement. Majority of players have theirs pointing into the floor when they're playing. The problem with that is, when they encounter an enemy, they have to lift up the crosshairs and then begin to aim. Keep the crosshairs at about your enemy's head height most of the times. That way, when you see someone you can start aiming and firing right away. You have a warlock. Choose your subclass based on how you play. If you prefer keeping your distance go voidwalker. If you like to get up in people's face, go sunsinger. For the crucible I prefer voidwalker. It has blink. You have to get used to blink. Blink is just a beast. If you find yourself in a bad position and you're swarmed, blink away. Keeping running. Make them chase. What I do alot, I run away. As I get around a corner, if there aren't too many, I turn and I charge when they're still charging at me. When they get around that corner and see me charging, they all panic. If there are too many, run and lead them to your teammates. Your teammates will pick them off one by one for you. A shotgun is the easiest thing to use, especially if it has decent range like Found Verdict. That's all I used until the last Iron Banner. Then I started using a sniper. I'd recommend learning to snipe. When someone sees your glare, it keeps them in check. And sometimes, they just leave you alone. Find a sniper that has maxed out stability so if you didn't get that headshot, you can fire two body shots quickly. That'll take them down. One more important thing is know your maps. There are areas on some maps that you have to be cautious of. For example going through that cave area around flag A on Shores of Time. There is a platform that people normally camp out and wait for enemies to come running through that cave. And bam, Icebreaker to head. You can even use these spots. If you're ever passing one of them, stop and spend 15 seconds there and wait. But don't camp - people won't respect you and if you get someone there, believe me, they're going back to that spot to see if you're dumb enough to stay there. Edit: A huge point I forgot. When you're in a 1v1 gun battle. Do not stand still and shoot. Move from side to side. Make a few of his/ her shot miss. And I would also advise watching a guy's youtube channels. Just search for Arctyc. He snipes alot, and those spots that he gets people, alot of people stay too long in those spots. I guarantee you that you'll catch a few there.
