I completely agree, the different grades are nothing but an annoyance. As a crafter I really don't make any gil off them since every crafter and their mother can make them and its just annoying to carry around 10 prism types when you could just carry 3. I have resorted to making them on a needed only basis instead of grinding 10 out and letting it sit on a retainer.

If you have a decent fc, like ours, ppl don't buy them either, we have enough crafters that we just say "Hey I put mats in the chest, can someone make me a blah blah blah prism" and its done.

There are plenty of ways to make money crafting, but its like when arrows stopped being an item and started just being obtained from our magically bottomless quivers, crafters went nuts saying SE is destroying their only source of gil, but it hasn't been an issue at all, crafters adapted and they still make money. In this case you can still make prisms but you only need to make 1 type instead of 5 so I don't see why it would be something to panic so hard over.
