Well i got beat but might as well hammer it in more. This is why you pay attention during high school math class kiddos. Currently, most of your stats come from melded gear. This means that there is a huuuuge curve between a vanilla geared person and a double meld person. Double melds, however, are not meant to be the standard. As it stands now its basically required for endgame content. To correct this, they are going to flatten the curve by making stat gains through levelling more meaningful.

This can be done several ways, from nerfing materia stats, to buffing stats in general, to giving us more points, to...well you get the point. Anyway the idea is to keep multi-melding as an optional goodie. Right now its not really like that.
