+1 to remove weaponskill recast time from RoF. Lower damage bonus to compensate. Also, rework One Ilm and Tornado Kick so that they actually see some use.

My biggest problem with Brotherhood is that it only really comes into fruition in 8-man content heavy on physical DPS, and is pretty garbage otherwise. I would prefer if its benefit to the monk would be normalized to work regardless of party composition.

For some napkin math, consider two tanks (~2.5s GCD), a BRD (~2.5s GCD, plus one use of Empyreal), and a NIN (~2.0s GCD). In Brotherhood's 15s duration, they would use about 26 weaponskills, 30% of which would gain the Monk Chakra, for about 8 Chakra total. A MNK at GL3 can fit 7 weaponskills into the duration. My suggestion would be for Brotherhood to keep its 5% physical damage increase in an AoE around the MNK (potentially including the MNK as well), but rather than recovering Chakra from allied WS, give the MNK a guaranteed Chakra every time they execute a weaponskill (for up to 2 if Deep Meditation procs as well), and potentially add an increased success rate for Deep Meditation for the duration of the effect to make up the difference. That way, it's less dependent on RNG and party composition.
