Shadow Priest - How much Spirit is too much?
As title says, I wanna know how you manage Spirit on your gear, if you do at all. Right now my itemization is skewed toward Haste, Int and Crit (hit is capped), 2 or 3 of my pieces have Spirit and to figure out how much is too much, I test my mana regen on a 5-6 minute fight, just making sure I never run oom with an expectation of at least 20% mana remaining at the end of a fight. In a raid setting, mana is more abundant but I have limited experience atm. I'm not sure now if I should just give up on Spirit or there's a golden ratio unknown to me.
This is not about rotation, I'm using my mana regen mechanics to their full extent.
