Other than armor, all stats will be useful to healers in Warlords of Draenor – although I can see armor sometimes being useful in specific situations (my undergeared healer had to STAM flask – yes, really – to survive later Accelerates on heroic Thok).
Will there be any secondary stats besides armor that will be useless to healers?
Nope, all secondaries besides Bonus Armor will be useful to healers. (Source)
From what I gather tank will have a unique secondary (armor) and healers (spirit), do DPS get a unique secondary?
Current plan is no. (Source)
