I really like the breakdown you've done of the changes to Monk throughout it's lifetime, and I agree, Monk is definitely in a bad spot as one of the now two "selfish" Melee DPS classes. I completely agree with you on the use Purification and how situational it is, and almost unneeded at this point, due to TP cost reductions. If anything, I'd like to see Purification be replaced with something to preserve GL, or at least maybe to remove it, but keep GL 3 stored until the next application of Greased lightning. I think would greatly improve the usability of Monks in boss fights where they lose GL stacks due to factors outside their control.

As it stands now, Monks are vastly outclassed by Samurai (Thanks 40k Direct Crits at level 70) and probably honestly need the same treatment as Black Mages need, a major damage boost to give them something to stay competitive with all the utility that other classes bring. It would truly be a shame to see such an iconic class fall by the wayside.
