I tought they were making spirit once again main mana ressource and were getting rid of mana per 5 rule, except for procs or on use. They have also removed any talent that made spirit worth for casters...and this will make me get rid of all my lock epics from lvl81.

But it's a lvl83 trinket, and blue for what it matters...meaning epic one is probably have more dodge rating and probably +stam or on use/proc effect.
