I have tracked weapon quality for more than a decade. It is cumbersome and tedious. 4 years ago I began simplifying my system without removing those essential qualities it featured. Old RQ remnants such as weapon tear and wear obviously had to go, as it slowed down the flow of the game.
I did not know any great replacements, so now breaking happens through the fumble chart (high percentage chance of breaking on poor weapons/items, low percent on better weapons/items).
Of course really bad weapons incur a penalty on damage (poor edge) or accuracy (unbalanced) in addition to higher break on some fumbles.
This is not nearly as realistic as my previous system, which took EVERYTHING into consideration, but it is alot more playable.
