I personally don't meld that much unless I want to be "totally effective", and even then I don't do raids or extreme so why would I even bother? I can only meld secondary stats and how many of them are actually useful? Exactly.

Melding itself is quite unpolished anyway: unless it's crafted gear you really can't put any main stats into your slots, cannot overmeld either, and when you upgrade you lose your hard-earned V grade materia. Talk about waste!

If you could meld more main stats into it - and also give stats bonus, like WoW JC (worst game ever, yadda yadda) used to do - on top of also being more lenient (overmelding feels like I'm playing a cheap p2w game without the % boost) and overall being "better", I can see more materia melding being done.

As it is, it's just pointless to even bother and whenever I can, I just sell V materias until I can upgrade my gear, which will be in months anyway. I can only see an utility for gathering, crafting and if you want to min-maxing your potential but beside these, what's the point?
