A very large amount of Monks do not use fracture at all or use impulse drive correctly. Many Monks apply there DoT's every other combo which severely cripples your DPS, where as the appropriate time to DoT UP is when you have BFB and/OR IR ready and your apply them AFTER you freshly apply dragon kick and twin snakes, where as so many monks apply there after a Bootshine combo. I could go on an on about how to correctly MNK vs the silly things most people do when playing mnk which results in terrible dps. Granted MNK does not have great team utility in end game such as coil, however when you are busy out-damaging every other DPS by several K, its a pretty fair trade. ALthough Mantra is VERY useful in coil, you just pop it on your tank between rotations like any other NON-GCD like Steel Peak or Howling Fist.

TL;DR If you think MNK is weak, L2P or pick a new class, your making us look bad.
