1) fast pace moving through area (especially in groups) the orange drop can easily fall off the visible screen
2) the dim orange text on ground can be missed
3) the always on item label in ground sometimes turns off on its own (I think this is a bug)
3) its a easy and quick way to view the cleared full and mini map for missed orange loot on the ground and go back and grab the ones you missed after dungeon is cleared
4) for barbs, this is super helpful, since the barb fights on skates, he is in the next room before you know it, just with whirlwind :P
ok, so this option to turn on a marker on the map for legacy loot doesn't exist, but wouldn't it be cool if it did???
