Can't really give you advice on rotation, you should of worked this out by the time your 50 really, I feel it shouldn't be something you analyze and pour over, should just know what to do by instinct ^^, people will debate till cows come home on their stuff, and what is better, I tell you just go with whatever you feel works, I just always make sure to keep twin snake, dragonkick TOD, Fracture, demolish up, 90% of time, sometimes they fall off for 1 or 2 seconds so its not end of the world, Also you can fit in 1-2 impulse drive EVERY combo rotation(if target is not running around everywhere (static)), Hope you work it out, MNK is fun and should be played from the gut


edit: just make sure your filling every GCD with at least something, and try to keep your GL on all time, dont sweat it when you lose it tho, happens often on primal hard modes!!!
