No doubt this has been reported before, but it came as a surprise to me. I found a weapon with decent dps (362.7) that has its level requirement reduced by 9, from 56 to 47. However, it will only show up when I search for level 56 weapons and not when I search for level 47 weapons (where it should show up near the top as it has almost double the damage of any weapons currently showing on the level 47 list).

This is preventing people from seeing the best leveling weapons in the game, not to mention making it difficult to sell weapons with reduced level requirements.
