I have ranged weapons filtered out and disabled “always show double rare”, so I didn’t see this item drop, but it still showed up on the map:
I wouldn’t mind removing these markers from the map altogether, regardless of filter or item’s quality. I am paying attention to drops. If I wanted that item, I would already pick it up. This isn’t Titan quest, where items had to settle on the ground (which took indeterminate amount of time) for it’s name to appear, making them easily missed.
