As a crafter im against reducing the prices. It would be cool to have 3.0 Sarpan weekly quests if possible just moving the NPC to Sanctum/Pande, but there is no need to reduce prices if that happens.
The only thing people most want from it is Fine recovery serum and Fine Recovery potion, which the first one has been confirmed that it drops from certain mobs and second one is not that hard to get.
Well, as a crafter, I can tell you that it’s not just about the serum. You also want to equip your alts and not run around dungeons with every character. And just because you know from Gee where the serum drops in Inggi, it doesn't mean that everyone will now go and farm it for hours. And where is the rest of the loot table for the other recipes? Oh yes, and you want the weekly NPC to get more coins, BUT then you could simply increase the daily reward. I think both approaches can work. Keep in mind the loot table is incorrect, and I don’t want to have to ask an admin every time where this and that drops.
