It's kind of weird how Horde and Alliance Shadow Priests have different gear. Alliance gets the RPPM caster DPS trinket, while horde gets the on-use versatility caster trinket. Not to mention for whatever reason, I have 2% more crit on Horde, but 5% more haste on Alliance before BG scaling.
Yes, this is ignoring the +% buffs you get from racials, if I add in racials it's an extra 1% because my horde character is a blood elf. But you actually have more raw rating depending on your faction.
