The game would be better without stats

[Lyndina]

I mean...there is a point that melds are basically useless. Every class goes for crit/det/Dh anyway. . Everything else...nope. Sure rare cases like monk and skill speed...but you could also give out gear with those stats on it. And in downscaled content (which basically every Roulette thing is), you dont get any use out of melded materia
On the other hand...we have no talent points nor anything that would make it an rpg with any choice at all. So just keep it in and still give an illusion you could change your playstyle at all by melding different.
