Hi there! Im wondering what you are did you choose for your spriest, im going with mastery because the ammount of crit you get its really small compared to mastery, which is really more useful (imo). Im going with mastery atm and i have 26%, but would like to see what do you think about it.
Mastery
+more divine insight procs, which makes us build up easily our burst-on-demand (Devouring plague)
+more FDCL procs, which makes us build up easily our burst-on-demand and gives us even more sustained damage
+overall more damage
Crit:
+if crit, more healing
+if crit, more damage
+a crit devouring plague + on-use can be deadly
maybe im missing something, but let me know!
