Well, every piece of gear (excluding a few of the accessories) has needed tier IV Materia so far. I've been lucky enough to only need 4 Materia IVs to finish. But, looking at server price and availability, 400k x 4 = 1.6mil. I just think this is absurd. I have a theory: I've seen several people buying materia, way more than they would ever need, and then stockpiling it to sell later. While this is legal, it's a bummer.

As for Luminary tools: I can totally understand not wanting to remove the achievement for 1.0 people. But, why can't they do something like add an additional effect, such as, "Upon using this tool, shard usage is decreased by 2 and crystal usage by 1." That's not game-breaking, removing one or two shards per synth won't break the economy, seeing as you have to use thousands to get the Luminary Tool. It also still makes it special for 1.0 players.

I also heard a rumor that the ovens/workbenches/etc. for Luminary were lackluster and tiny. This is also disappointing.
