The maps in destiny are not big enough to offset the low range Stat of the Mida. It's optimal at every distance because it still fires fast enough to compete in close quarters (except for TLW and Doctrine, Necrochasm) and the sniper lanes in destiny are all very small. It still out guns 1kys because of its high caliber. It literally makes the next highest impact archetype of Scouts pointless to use because it takes the same amount of body and headshots to kill. Even the long sight lane on pantheon still is a 4 shot kill at that distance. Everything not named TLW or a bullet hose AR is sub-optimal to the Mida because it's drop off isn't high, and it's fire rate is still high for a scout. It is the best gun in destiny right now, and outside of those 2 guns mentioned above, by a pretty wide margin too.
