Done it on the PTR, MP10 Ghom/Raka uber pair. Needed sweeping wind too, seems that WoL spam on its own is still not enough with dual LS (net negative life sustain without using Serenity) despite getting buffed in the PTR, and LpSS alone will not replenish life fast enough (especially with the Raka charge and little globs and dogs thrown in).
On the other hand, LpSS as secondary sustain is just sweet. Use left and right mouse click, use 1 hand to party chat, and still comfortably clear that Ghom/Raka test.
Overall good guide Fuzzy. I've always felt that LpSS is unique to Monks, just like Barbs have LS belt and passive. Only wish Blizz changes it to scale somehow to be as effective.
