I'm just wondering if this player's post still holds true and reliable currently in-game, as far as best way to meld your crafter gear with materia at 50 goes?

I kind of took a break from the game after 2.1. I've been back for quite some while, but now just began crafting again. I've had a 50 ALC, but now leveling GSM up to 50, currently just above 30. I want to make sure I have all my 50 crafter gear, melded the best way it can be. Also, is the 50 gear still the best way to go, there are new higher level crafting items I believe? Could you fill me in a little with what's new? Thanks!
