While you are at some disadvantage, i would not say it is unfair by any means. I like the unlocks myself, really just adjust your play style to what you have or what you can do with it. Just have ironsights? Put in in semi auto and stick with you team, or be more stealthy. I did pretty decent with the ironsights, just remember this isnt cod or something. Tactics are more important than an acog with the best AR you can get.
