The patrician's set isn't that hard to make, and meld to be very useful. If you're 50 in all DoH, then a "simple macro or rotation" is NOT what you need. You have every ability at your finger tips, learn to use them. Look at the 100% rotations you can ifnd in these forums, and tweak them. Use "Comfort zone" when you get "good" condition and you don't have a staeady hand, or waste not up use "tricks of the trade" and you should be able to have more cp than most rotations require - which also will allow you to use ingenuity II instead of I, or inovation, or advanced touch, or basic synthesis...

2 star gear can be huge profit, but isn't worth it if there are lots of sellers constantly undercutting. See if there are any pieces with just a few sellers. High risk, not always high reward. Materia is worse risk/reward IMO.

One star mats have been profitable to me, just not always the same ones, and usually in small quantities. less than one star mats have been great too (dodore leather, shark oil). Less than one star gear has been profitable too (Mossy Armor costs me like 50gil to make and I'm selling for 10k). It's not super fast, or gobs of gil, but I pretty much always have both retainers selling the max number of listings. Be a savvy buyer, so you're buying materials low.
