Gil sinks, yes please.

That said, one time vanity gil sinks are not the way to go. Yes, they take a big chunk out of some deep pockets right away but a far more efficent sink is a repetitive one that impacts the broader populace. Give us expensive consumables in the veins of cordials and potions. Let us trade larger gil amounts for MGP at higher loss rates. Make an item that increases overmeld % chance success and have us buy that. Basically make things every player can appreciate and get gil from everyone.

Gil sinks for the ultra rich...hmm, let you pay for extra retainers in in game gil maybe?
