Problem: Items are Worthless

[Solipse]

This is why the soulbound/bind-on-equip system from WOW works so perfectly. Once someone buys and equips an item, it's removed from the market permanently. I would wholly be in favor of a similar system for FFXIV.

That's not why WoW's economy works.

I detailed it earlier - just adding soulbound items will not help at all. The reason being is that currently, more items are produced than can be consumed. This will always be the case in a game where crafting is a major part of the basic gameplay. There needs to be a reason for items to leave the economy. If people make a thousand crab bows but only 50 of those are bought, then there's a glut in the economy and the items become worthless. Soulbinding items would only remove those 50 from the economy, the other 950 will still be there.

This is the case with literally every single piece of equipment.

The reason why WoW's economy is healthy is NOT because of soulbound items - but rather because of the ability to disenchant gear. When the market becomes glutted with cheap items, enchanters buy up all the cheap items and break them apart for enchanting materials. THAT is the entire reason wow's economy functions. The whole system is a checks-and-balances type system that prevents massive deflation.
