Yeah... no, the idea that your equipment can permanently break based on a % check is insane imo, it would cause so much stress on the player's part. It should be that, imo, the lower your skill in repair, the lower cumulative amount of repair per click. Obviously, the higher your skill the higher the cumulative number. So say your sword has 20/50 durability, and your skill in repair is 1, each "repair" you do to the item is an rng between, say, 13-17. At repair 2, the % increase is something like 20 or 30%, so that is a 16-20 repair.
Yes, please replace the slightly inconvenient and occasionally annoying mechanic with an absolutely terribly annoying and disruptive one. Because clicking more is more fun right? /sarcasm
