Actually there is only one way out of this mess for NC west if they dont want to recall all the items that was made by abusing the system.
They need to put event with good chance to go +++ on alot of stuff or let the game drop +10 shillien crystals and +20 cloaks.
After this is done they need to shut down the restoration system once and for all, because it was unfair from the start and totally unwanted.
Like this the ppl that abused the system win in both ends...
