PVP, Materia, and a "Real Living Economy"
Yoshi P claimed that PVP would create a "Real Living Economy" (link) However, currently the economy seems to have stagnated due mainly to high housing prices causing people to horde gil. Besides a few entry level PVP gear that can be crafted, as of now in 2.1, it seems PVP really has very little effect on the economy. However, after doing some research on PVP and materia, I believe that I have figured out Yoshi's plan for PVP and the economy, and I'm not certain if it has been fully implemented yet.
Everything from this point on is an educated guess on what I think Yoshi's grand plan for PVP and the economy is. I've always been fascinated by the economy in ffxiv, which lead to me level all DOH and DOL to 50. I've been "playing" the market for a very long time, since early in 1.0.
First of all I should point out that I do not PVP. However I have heard that there is ilvl 90 PVP gear that can be melded with materia. I also heard that there exists materia specific to PVP that provides resistances. I don't know how to obtain this armor, nor do I know anything about the specific stats, but I believe it is safe to make three assumptions concerning PVP gear.
1: The stat caps for secondary stats will be about the same as the secondary stats for AF2 and Allagan ilvl 90.
2: Ilvl 90 PVP gear requires materia in order to be best in slot
3: Due to the extremely competitive nature of PVP, players will be highly motivated to fully meld their ilvl 90 PVP gear to be best in slot.
Let's assume that you are a bard and that your ilvl 90 PVP pants have no crit attack. Bard's Tights, the ilvl AF2 pants gear for bard has 34 crit attack. So if you wanted to cap crit attack materia to your ilvl 90 PVP gear you would need to meld 2 IV materia, 2 III materia, and 1 II materia to reach this cap. Or you could meld 4 IV materia, (one of which will not be fully utilized) and still have a materia slot left over to use for a different stat. (which will probably need another IV materia) So in order to fully meld ilvl 90 gear, most likely one would need to penta-meld IV materia onto their gear.
I have 5 IV materia on my gryphonskin kecks, which have 2 materia slots. If I recall correctly, the percent for the last slot was 8-12%. So if people need to penta meld all of their PVP gear, they are going to be blowing up a lot of IV materia. (about 40-60 per gear slot on average I believe) This would create a HUGE demand for materia. A huge demand for materia, would mean a huge demand for crafted gear to spiritbond, which means a huge demand for mats. Now granted, there are resistance materia that come from PVP, so I'm going to make a 4th assumption, which would make both the resistance materia and regular materia viable for PVP
4: Stat materia are a requirement for BIS gear. However, there is a cap for the resistance materia and after a certain point of decreasing marginal utility, it is better to use other materia
However I don't think Yoshi is going to stop there. I believe that PVP will, in an indirect way, increase demand for philosophy tome crafting items. I've heard rumors that you can convert ilvl 70 crafted gear, like Vanya gear, into tier V materia. Even if these rumors are not true, I believe that the ilvl 70 gear will eventually be a source of tier V materia. Tier V materia was in Beta, and I have a screenshot of an example below. The requirements for the base item for the materia is ilvl 90, which happens to be the highest tier available to PVP. Also tier V catalyst was given to players as part of the main story line. So if they actually do introduce V materia, and it comes from 2 star crafted gear, (perhaps with a 20% chance a ilvl 70 gear will make an V materia), then the market for 2 star crafted gear will also recover, as will the market for philotomes to make those 2 star crafted gear.

So hopefully I'm on to something, because these ideas I described sound awesome to me, and they sound like they would actually create a "Real Living Economy"
