Since Abyssea... well, let's not joke with ourselves...
Selling shit gear to NPCs is a big cause of inflation.
It creates currency, which can build incredulously fast... especially given how much abyssea rare items suck so bad, people won't pay more than 2-3k for them. Oh, but NPCs will buy that trash for 5-9k. And doing abyssea parties? Stock up on dominion points. Buy those augmented weapons, I think the scythe NPCs for the most? Maybe the lance? Whatever. I filled my inventory UP with that trash. (Kept one lance! +12 DMG +7 STR?! JEEBUS!) Aaand yeah, a million gil later I could finally afford to buy the spells I haven't been able to afford for so long.
I see serious inflation about to happen. Abyssea items, maybe not so much... that stuff is almost cake to get. But anything crafted or pre-abyssea might start jumping up in price. Cause everyone's getting gil like mad gil-loving hounds.
So... here's some ideas for cutting gil down a bit... (and to also solve some annoyances)
1) Bazaar fees. Bring back the 10% tax. Heck, start charging "AFK in front of the mog house in port Jeuno" fees. This would clean up port jeuno...... a bit. And take a small edge off the gil-crisis looming in front of us.
2) Stop the NPCs from buying Augmented items. They're augmented. We can't trade em... can't sell em... but NPCs want to buy them- and snatch em outta our bags? Great... but its a lot of the money problem.
3) Lower the value of a majority of items released since abyssea came out... I know they enjoy raping us for common items / lowbie junk... but I feel like the roles have reversed, and I'm not so comfortable raping a NPC for all the gil they can muster.
4) Booze. Tons of MMOs have bars / taverns / what-have-yous. Let players purchase some 'brew' and drink that stuff for all kinds of effects! Additional effect... blindness, flee, gravity, etc. Totally random effects, and it would be great to just toss some gil down for drinks with friends.
5) More food vendors, maybe NPCs with daily specials- a food item and a drink for a bargain price... get people to start using food enhancements again!
6) Weekly mini-Mog Bonanza. Simple prizes, vanity keepsake house decor, grand prize could be like a kupofried ring or something. Maybe 1 ticket limit per player. Heck, if this was a daily thing, it would suck so much gil out of the player base! 10k a ticket, 7 days a week- 70k a week.... Oh yeah
7) Face / Hair "restyle / makeover" total vanity thing, players have wanted for like Ever and a day, maybe like a 50,000 gil deal.
Okay- everyone else, throw suggestions out there for ways to keep the low prices we'd been getting Low, and maybe down to record lows! There is no sense in flooding the players with gil, items are just gonna shoot up in price again!
