Not quite as strong as a hybrid, even in JQ, but can prot against JQ gimmicks which is important. Remove hex seems to only be on the build because holy veil requires more brain power to use. Spamming the bar will definately make you less effective which most of the players in JQ do.
Compared to the RoJ build, using the same professions and some of the same skills, this is really an inferior build. The RoJ build is useful on both an offensive role (solo capping shrines) and a defensive role (healing/boosting NPC's and Carriers). This is only viable in a defensive scenario, and when the game needs you to be proactive you're just borderline useless (ie protting/redbarring bots).
While not being an inherently bad build, for a Monk player the RoJ build is just the superior option.
