Stop with the pay to win advanages for retainers, suggestions on fixes

[Reynhart]

So if we take the time that I need to sell the stuff as the win, I win.

Yet again, you win...more gils. In a game that requires far less gils than any serious farmer can earn, even with the Entry account, because new competitive items are only released every 6 months.

Selling items on the market board is intrinsically competitive. If you have two items listed on the market, one each from a different player, both players are competing to sell that item.

You're right, but how many retainers you have is irrelevant. What changes is how your strategy, by selling maybe a little cheaper, or selling units or packs, etc...Economy is far more complicated than "more shop than a contender = more benefit"
And again, the only thing you gain are gils. Gils are not a goal.
