This thread is making me laugh. Ninja has a rather high burst, and a rather high sustain. Monk has a average burst with perfect balance, and an exceptional sustain, but it relies on keeping GL3 and your tank not spinning bosses. Final coil is not the only content that matters, and if you look closely at all three of the new expert dungeons, ninja is severely outperforming DRG and MNK due to the movement and fact tanks unwittingly spin the hell out of those bosses.

Stop acting like coil is the only content in this freaking game that matters... SE has the data they need, and they will adjust it accordingly.
