Auto Rifles in this game are very consistent. I just got my SUROS a day ago, and it is a very consistent weapon. You rarely miss with it, and if you do, there isn't a huge penalty. A weapon that is so consistent (and easy to use) should not have a kill time that is so high. On the other hand, people complain about hand cannons, but hand cannons are VERY inconsistent. When I first started this game, I had so much trouble aiming with hand cannons. Yes, they have very fast kill times, but you have to work for that kill time a little more than you would an auto rifle. It's kind of like how ARs and BRs were in Halo. It was hard to miss with an AR, so you could always count on getting a kill in x amount of time. BRs were less consistent because you actually had to aim, but if you had to skill to aim, you would kill faster than an AR.
