No offense but there are more through, more accurate guides all over the internet. This looks like you just copied the wowhead guide into text…
For priests it’s even a little more complicated than a just pure stats (which most raiding priests already know btw)
For one you’ll almost always want Hazzrahs trinket, and if you’ve got that any of the ZG pieces are better than transcendence. And either way, you’re going to keep the 3 piece transcendence probably until you down KT in naxx… So the offset pieces are just going to be what you can fIt around your 3 piece.
Trinkets are also pretty fluid. I’ll swap Hazzrahs for Blue Dragon or shard depending on the fight and could see swapping Rejuv for Brooch on some fights when I get it. You’re almost never going to pop a ZG trinket then swap though btw. If you remove it you lose the buff and the cooldown is 1.5 minutes so it’s not like flask where you’ve got a lot of CD downtime
If you want to read up some, I’d recommend the priest disc if you want some actually useful info.
