It is the crafters right to refuse repairs without payment of mats or the Gil sum total of said mats.

With that being said if someone offers payment the crafter has no excuse outside of being stubborn. Arguing that it would take too long is nonsense as it would hold up the group longer with your being stubborn. If the person in need of repairs lacks payment and refuses to progress it is well within the groups right to vote kick said person. I'm betting most would offer to pay if it meant moving the group along seeing as the mats are dirt cheap. I would probably do it for free as a crafter and politely tell them to make sure they have it repaired next time. This argument is nonsensical as an excuse for not implementing a request repair feature. It's as simple as not being an ass regardless of who is the crafter or the person in need of repairs.

Please stop with this as it is missing the point of the topic at hand which is convenience and only aims to derail the topic.
