Repairing: Even better than before!

[Nasibihc]

Just got a little thought about when people repair things in real life and they say something along the lines of "I just repaired my boots and now they're even better than before!" So hey, I thought, wouldn't it be neat that when you're repairing an item in game, it'd have a very low chance like 1/100000 or something small, to actually result making the item a +1 when repaired making it "even better than before!" ? Of course the percentage is so low that you couldn't possibly abuse it, but hey, at least it'd make some people happy sometimes when it does happen? Also toss in an achievement for this if you do happen to get this done sometime!

Anyways, what do you think of this idea?
