Having played a Holy Priest for 2 years as my main but for the last year had my main as an Enhancement Shammy my priest knowledge is a bit rusty. I understand that the Disc tree has become viable as a raiding tree although more in the role of damage mitigation than out and out healing.
What I would like to know is what role Pain Suppression plays in a Disc Priests raid arsenal? From the tooltip the 40% damage reduction sounds good however the 5% threat reduction sounds bad if used on the tank. Our disc priest seems to suggest that using it on the MT is fine as he emphasises the role of the 40% damage reduction as a melee dps class these days the 5% threat off the MT can cause issues in some fights of threat capping. Yeah I know WTB better tanks.
Question is : Should a Disc Priest ever be using Pain Suppression on the MT? Or should it only be on others?
