For my resto druid I have 2 tyrannical gladiators insignia of dominance. They are not unique to equip but do they work together? I know they don't stack but when one trinket goes off and expires, the other might work sooner than if you had just 1? I guess what I'm asking is if I have 2 of those equipped I will spend more time healing with the extra spell power than if I had just 1 equipped. I've tried to look but I don't see anything.
