need some suggestions to improve my nun (female monk):
(stats shown are unbuffed, no mantra no enchantress passives on)

basically i can solo all bosses, kill most elite mobs, but i have issues with plague, descrator, fire-chain mobs. simply impossible to kill them without dying at least 4-5 times.
setup: i am pretty much set on doing wep+shield (51% block just wins me over), but if there is a viable dual wield build right now, please let me know. thanks!
