I often see posts where we ask what is the main stat for a discipline priest
some answers:
intellect > spirit > mastery = crit = haste;
intellect > spirit > mastery > haste > crit;
intellect > spirit > haste > mastery > crit;
now, ok for intellect and spirit but my reasoning was,
if we follow the first case, we would have 3 states in an equivalent manner which results in a loss of statistics -> not fast heal, not good crit, decent shield
if we follow the second case, we have good shield but we can not rely on a mastery that takes its maximum benefit from crit, that would be the lowest stat (proc aegis) or have a good mastery is sufficient for PW:S? (TLR without the crit i do not believe that mastery is so efficient)
If we follow the third case, we have good haste for heal/smite etc, decent shield, really low crit
tank healing example haste = faster heal + more benefit from "Strenght of soul" --- mastery = strong PW:S but with no crit -> low chance of aegis
raid healing example haste = faster PoH and more shield from it --- mastery = strong shield from PoH
Im wrong? someone can say definitely which stat should be better in average?
