For all of those suggesting the percentage for forbidden materia craft success be raised, I wholeheartedly disagree.

If they raise the percentage then they'll lower either stat effectiveness or materia stats. I'll take my +20 STR attached to 7 different pieces of armor = +140 STR and be happy with that.

To those that want double or quadruple that they can deal with the risk in my opinion. Until they release content that requires a full party to have those kind of inflated stats I'm really not concerned and I don't think you should be either.
