I'd love to improve my communication skills but I really did not think I was that unclear. My bet is that most people think the amp trinket doesn't add to spirit even though it is clearly written on the tag. I'll give it another shot at explaining what I'm talking about.
I am talking about this trinket:
Purified Bindings of Immerseus. This trinket procs an intellect buff from attacks. Due to this, this is the caster DPS trinket.
The actual amplification effect is as follows (for the 553 version):
Equip: Amplifies your Critical Strike damage and healing, Haste, Mastery, and
Spirit by 7%.
Thus, for Elemental, Boomkin, and Shadow, this trinket actually gives you hit rating as well. This is because for Elemental, Boomkin and Shadow, Spirit gives you hit. This 7% spirit is completely wasted if it's given to a mage or a warlock.
I will once again link the trinket I'm talking about
