Repair NPCs in Dungeons

[Felis]

Minimum ilevel already prevents this, and has prevented my friends from derping before.

don't exist for lv 15-47 and lv 51-59 dungeons

I used to wonder why too, then I realized the answer is RMT.
RMT A queues into dungeon A - RMT B miraculously makes it in too. RMT requests repairs from B, offering 100k or whatever monies to B. RMT B repairs and leaves 100k richer. They have managed to move monies between servers (admittedly just within the data center) but they can move gil. I wondered why they don't just cap the repair reward /shrug. It's one of the few things I miss from 1.0.

SE should just do it without involving a payment.

Player A want his gear to get repaired in the dungeon and activate a repair request. Player B right click on Player A to repair all the stuff that Player B can repair and the needed Dark Matters get automatic removed from Player A because Player B used the Dark Matters of Player A for the repairs.

No payment or trade involved
