I enjoyed it while i played it, but the leveling aspect of it is just so time consuming 74-75)75 being max level) takes probly 12 hours+...which is not worth it to me, that's why i crafted(you posted, you know what i'm talkin about), it's sort of like magic finding in D2 because there's a chance you could make a high quality version.
For Example:
Baseball Bat- takes a piece of wood to make.
you could normal quality it, and make a lil or no money, or possible lose, but there's a chance if you're so many levels above it, right moon phase etc. that you could craft a Baseball Bat+1 yielding higher dmg, less delay, etc. and +1 usually yield boatloads more profit.

Baseball Bat is an example not a real item in FF, lol
But doing mission/ranks and stuff like that is fun with friends and linkshell members, but like i said above leveling jobs just takes so much time i never enjoyed that part
