Items:
“Resplendent Vessel of Ronka” selling for 25 million gil (gold version of “Great Vessel of Ronka” mount)
“Gilded Mikoshi” selling for 50 million gil (gold version of “Mikoshi” mount)

Benefit:
A way for players to spend large amounts of gil reducing inflation in the game's economy and take the gil out of circulation.

Drawback:
Prizes that will only appeal to a small percentage of the population due to items being a recolor of something they already own.

Solution/Suggestion:
In my opinion the addition of the new gold colored mounts is a great first step into the issue of inflation in the game's economy. However, I feel that a recolor of mounts players already own for absurd amounts of gil will not convince enough players to buy them and will do little to take gil out of circulation.

I suggest, a way to peak player interest by adding something they will be more likely to spend large amounts of gil for. In my opinion I believe adding items that are currently only available from the Mog Station to also be available from Luxury Traders for gil. Despite the controversial topic of buying things from the Mog Station with real money, I believe having options is a good alternative. If a player has the option to spend real money on an item or spend time earning money in game for the same item, they are at the very least given multiple options to gain something they want.

As for the implication of this idea on Square Enix's part, I feel it much easier to add items they have already created models for and animations for instead of trying to create brand new items. Although, I am not against the adding of new items, these are always welcome. I am just trying to suggest the easiest alternative to achieve all the desired outcomes.
