I didn't even read all of it, and I read op about 5-7 times. Shotguns in Destiny are debatable between skill. If you want to use Battlefield as an example, I've tried using shotguns in it. You're shot almost always. Sniping in Battlefield is relatively easier than Destiny, and actually a little similar. Similar only because it also takes two shots to kill someone unless it's a headshot. Battlefield has gravity and damage falloff. I can't tell you how many times I've missed a sniper shot because I misjudged the distance. In Destiny, the range of snipers is ridiculous. Not to mention the maps aren't half as big as maps like BF3 Firestorm (I think that was it). In Battlefield, you have utilities to secure your position; the T-UGS in BF3 was largely ignored by many when compared to the Spawn Beacon. It helped me a lot.
