PVP Materia

[Alzelia]

I dont PVP, but as a crafter, I'm very interested in materia and PVP. I saw both ilvl 70 and 90 can be melded. Before 2,1, 2star ilvl 70 was the highest ilvl gear (70) that could be melded. My Bard AF2 pants have 34 crit. I would assume the stat caps for accuracy, crit, and skill speed would be the same on bard ilvl90 PVP pants and chest. It would take 2 IV, 2 II, and a II materia to reach that. It seems like the absolute best emelds for PVP gear would be penta IV melds. I know there's resistance materia, but do you really need it in every slot on every gear? Why not meld Vit to Bard jewelry for more HP? I'd love to hear what you guys do for melds.
