I'm not saying that they're going to go ALL the way back up, but I sincerely doubt that they'll all settle as low as 10% of current value. My point was that quest rewards and NPC prices have increasingly insignificant impact on a player-driven economy as the game goes on. FFXI demonstrated this significantly. Prices on the auction house were vastly different from anything dictated by NPC prices or quest rewards (notably, absurdly bloated by comparison). I fully expect the same thing to happen in FFXIV. Eventually, prices will go up driven independently from whatever prices SE tries to artificially set. It happens in just about every MMORPG with a legitimately robust trading system between players, and I, for one, very much doubt that FFXIV will be any different.
