PB is already used, situationally, to do as many Leaden Fisted Bootshines as possible as a big DPS increase heh.

As for Monk needing a big rework... Uhhh... without changing the core of the job I don't think that will go anywhere. If anything, I guess they could rework it back to a 1.0 style Monk, where each of the Fist Stances provided some sort of damage boost or advantage over the enemy. In the case of modern FFXIV, we'd want it to be damage boosts or damage phases. Fire could be a GCD spike phase, Wind an oGCD rapid fire phase, and Earth would be the default standard phase, keep the built in mitigation just for kicks. I guess this would make it like a melee equivalent of Bard almost. /shrug I enjoyed it when I raided Edens 1~4 Savage on it. Started playing it back in Second Coil.
