This is probably a pretty noob question, but this is my first time getting to end game in ffxiv. I play AST/SCH (soon to add WHM as well) ilvl 220 (yay for shared gear!). Now that I'm getting some pieces of gear that I will be keeping longer than a couple of weeks I'm willing to spend the money to meld materia. I just assumed the best thing to meld would be Mind, come to find out when I went to meld it that all of my gear is capped on Mind, didn't realize this was possible. What should I be melding instead? Also, as an unrelated question, is there an ilvl recommended for beginning to run Midas Savage? I believe I read that it doesn't have an ilvl requirement to enter, but what is realistically necessary to be successful?

Thanks guys!
