Breaking Down Items would it work?

So i was thinking, would it be a bad idea if a "breakdown item" feature was introduced.. like.. take Vanya robe of healing for example. you choose to break it down and depending on your control you can get 0-100% of the items back that went into making it..

the reason why i suggest this feature is what if you had that really annoying RNG experience which left you on 20% HQ or if a 98% decides to NQ.. you could attempt to get the items back..

i am no expert on how the markets work but i guess this could mess things up cos you could buy vanya stuff and break it down into vanya silk etc.. i dunno just something i was thinking about

Nope, just no.

You'll see a 20k HQ Vanya Soon if that's the case. (might be a bit exaggerated, but you see where I'm coming, yes?)

I'd rather have a "Convert high ilvl into 2 or more materias" feature, that way it'll be reasonable to actually convert i70 (which is the highest atm) to materias.

yea like i said i dunno how markets would work in this situation thats why i thought i would ask.. it just occured to me lol

A known money making method in FFXI was to break down leatherbelts bought from NPC (300Gil) in San'O to sheep leather (100G) and iron ingots (1000G), depending on server.
Basically flooded the market with raw mats.

Since ilv55 gear can be converted into tier IV materia (can only be melded to ilv70+ [ilv55+ for crafting materia]), I would assume when ilv90 gear with materia slots and tier V materia are introduced, those ilv70 items could be converted into tier V materia. Until then, since the only place to spiritbond ilv70 gear is coil, I would assume we're not really supposed to convert the ilv70 crafted gear (unless you really want tier IV materia and have a group to grind turn 3 with).

My point probably isn't clear, but, what I'm trying to say is that, in the future, the materia that can come from ilv70 crafted gear may be worth it to convert the gear. Also since by that time, 1125 ToP might be obtainable in fewer than 12 dungeon runs, or the prices of some of those materials may be reduced. And if we can relatively easily convert it into worthwhile materia, we wouldn't really have much purpose in breaking it down to materials.

But, that's a ways off, and these are just my thoughts.
