That's so true though. I do sometimes, but very seldomly.
On the Highrise, I was getting owned, but there was so much going on outside the game(IRL), I wasn't warmed up(still haven't) and on top of that, it was lagging so bad everybody, including myself, were all over the place.
Not making excuses, but I have to explain myself why I was playing like somebody completely new to the game in that match. And Drag thought I rage quit, but my friend who was in the game, which was whole another situation with us getting separated, he backed out, then re-invited me, so that's why I left. I had no idea he was even in the game, and I saw no replays, as I was barely paying attention to the live game.
On the M16, I got the holographic sights right away. While it feels like the spread pattern is tighter(get your mind out of the gutter lol), the gun is so ineffective with the slow connection, I have moved on to TAR soon after that Highrise game. I tried Blinging it with the halo-silencer, but that totally killed the stopping power over distance. On Estate, I like to snipe with ACR or SCAR. Maybe it was the three round burst vs full auto, I don't know, but I struggled on long distance sniping targets behind cover.
TAR felt a lot better with the red dot, surprisingly. But since my goal is to equip it with the silencer, I took it off to get use to the iron sights.
