Ok so i tried this out with tape and a sharpie on a killzone story mission and i have to say... Anyone who buys this thinking they will have an advantage is mistaken. While this may be different for other games but i am talking about my experience on killzone. Using a sniper i would only hit if it i got lucky at 3-4 feet away and at any other range its a guaranteed miss especially since you get no zoom without aiming. I used a shotgun which didnt change much because its a shotgun it only works at close range and its a burst shot so its going to go everywhere. I used several assault rifles and its only accurate at close range while medium range its almost always a miss. The only gun i tried that this actually worked with was the machine gun called the purger. The purger has no sight but gives a crosshair if you gave that setting on. And that crosshair in-particular is one of the best being 2 horizontal lines that have a small space between them and in that space and slightly above is the dot. And using that machine gun regularly and with the dot i can say it doesn't really need the dot as long as you use crosshairs. The only reason the dot works for the gun in the first place is because it has no sight so it doesn't cost precision if you dont use the sight. So anyone relying on this will result in his or her downfall. I believe destiny does cost you precision if you dont aim although i understand concern when people could use this and see the radar at the same time. I doubt it would be effective on destiny either and id be more concerned with the sniper rifle that lets you aim and see the radar at the same time we could preview during the beta, because that gun is going to be a beast. And as far as the hipdotsight, we dont have anything to worry about as they are going to be free kills Edit: this also works well with pistols at short to medium range, but if you're against a pistol you are almost always going to win with any gun thats not a pistol as long as they dont get a headshot. (If neither of you miss any shots and you are both shooting at full speed)
