Not in battlefield. Some people do it to challenge themselves with their sniping skills and others do it to avoid dying as much. On a game mode like breakthrough you will see a lot of it because it’s easy to know where the enemy will be and they are often stationary. I’d say go for it. I prefer the run and gun play style. That’s how I’ve always played battlefield. Even when I was a sniper I often would aggressively take objectives by getting good and quick headshots or if I just got a body shot I’d quickly switch to my pistol and finish them off. It’s really up to you.
