I experimented with MNK for a little while (got it up to ilvl 80) a few months ago. What some people fail to realize is that you get accustomed to the positional requirements as you're leveling up the class/job, so by the time you hit lvl 50, everything is second nature. The only reason I stopped playing it is because my hands began to hurt after playing for a few hours straight on a small PS3 controller. With Ninja being position-dependent AND me now having a PS4, which feels a lot better in my hands, I'll be making a return to melee DPS when I'm focused, and SMN/BLM when I feel lazy and just want to sit back and pew pew stuff.
