Hand cannon...bloom?

The more you shoot the less accurate it becomes. It makes sense on paper, but it does weird things in destiny to hand cannons, most popular issue is dubbed 'ghost bullets' as shots perfectly on target will seemingly miss. Another is where your aim assist will behave strangely and maybe even shut off, causing you to swing past target when trying to recenter your aim each shot. You can even see it happen as you fire as the sights while aiming will spread out the more you fire. The precision archetype struggles least with this as they are deliberately designed with tight accuracy, so the issue is minimal. You can see this too with the hip reticules: 180's are tight circles, others are basically standard. People were arguing for the removal of this after Thorn came out because it really craps on the weapon's potential. It's been a problem before in D1 when they tried putting it in and everyone got mad, so they undid it.
