Only thing I don't like about materia system is it encourages you to wear junk over good gear, because no one wants to sit and kill mobs for hours to make materia. I'm going to end up crafting in junk and turning it into materia instead of using my Dodore Doublet.

Going off the fact I can gather or craft about 1.5mil in 3 hours on average and you can only turn 7 pieces into materia at a time I'm expecting materia to cost around 200k in effort. Demand for the trash gear you're turning into materia will go up too so a piece of grade 4 materia could set you back maybe 300-400k.

On the plus people with half a billion gil finally have something to spend it on and that gil will re-enter the economy. I'm undecided how much I will throw at it. I think I'll start off playing it safe, make a plan of action for optimal setup vs cost and then dive into it. By then people running materia bots overnight will have hopefully brought down materia prices enough to gamble on those +5s.
