Scope design flaws makes aiming really difficult

are you playing on 15 inch CRT monitor or what? Scopes are fine , maybe try full screen or higher rez ? 

play with a controller...I hear it has auto-aim.

That's kind of the way all the sights are. I too prefer the options with finer dots/crosses in the center.

I think there's an argument to be made that having some kind of bum options makes the better ones you unlock later worth pursuing. If they were all more or less the same, there wouldn't be much of a sense of progression.

Personally, I'd be cool with everyone just having everything unlocked off the hop and the progression being cosmetic stuff/player card swag. That'd be pretty A-typical for a modern Battlefield though.

I'd guess that the sights in game are a pretty faithful recreation of actual sight. Their weapon models all seem bang on (excluding the couple that are totally made up). I'd be surprised to learn otherwise.

Did you look at the screenshot? The reticle is bigger than the target. When you place the reticle on top of the target you cannot see it. It doesn't matter at all whether  my screen is 100 inches or 10. Still the reticle is bigger than the target I'd like to hit. Dots on DMR sights are so big that you cant tell where you are aiming if the target is beyond 40 meters or so. It covers like 20% of the whole persons torso
