The job has a learning curve to play proficiently, just like every other job in the game. This job has its steepest learning curve around hitting positionals and getting the flow of how your forms change the flow of your rotation. But as was stated, this is made easier once you just know how the boss's hit ring works. They tell you exactly where the rear ends and the flank begins.

I picked up the job back in Heavesnward and it took only maybe a week practicing for it to click and I was able to go about hitting the right position on the boss with the right move. Also remember that unlike it's other melee counterparts, monk has a VERY empty kit outside of its positional requirements. It doesn't have a trick attack window to plan around, multiple jumps to weave into combos, sens and kenki... it just has its chakras that generate randomly. If the job had the positions removed it would immediately become the most boring job in the game to play.
