Ok, I think it would be so awesome if you added a leveling system to the Weapons. The longer you own a weapon the more XP it gets. I think the ranks should go by stars. A 1 Star would be the first level and a 3 Star Ranked weapon would be the highest. The higher the Weapon Rank the more useful it is. Even Ascended gear. Like if a axe was higher ranked because you hade it for a long time after you've repaired it and kept it safe you'd be able to get the highest rank axe which increases let's say all tel he weapons stats by 5% for the first rank 10% for the second and 15% for the third. And if you lose the weapon or item such as an armor piece you have to repack the weapon.
People loose stuff all the time so I think it would be a fun feature.
