Yeah, just use mastery, they actually did that for a few specs. Said X stat is most important then chose to put a less important stat piece.
Um rogueXmage is difficult for priest, you are forced to pain supp the first dance and after you live DRs are reset and they can just kill you with 2nd dance.
If you can gain combat by mass dispelling them in stealth thats big so mage cant get a free opener. If you arent sapped pennance for grace stacks then shield + renew before they open.
Be on a pillar with your back to it, when able use inner focus for the interrupt immunity so you cant be silenced and fear them asap. They probably trinket. Your partner needs to interrupt mage and peel rogue. Rogue alone can solo you once your cds are gone so peeling him takes priority. Without wound poison and rogue to hold you in position you can just spam dispel yourself and keep out of mage los.
Dont overlap things like using trinket, PS, barrier youll need some of them for 2nd dance. Normally just pain supp at high hp will get you through 1st dance.
When 2nd dance is available again you should try to hold a global so when he hits dance you can throw barrier down before garrote hits you. If you can barrier at high hp and still have trinket or desperate prayer you can probably live unless they get a super clean rotation on you. Los mage. Dispel your partners cc = healing on you because he can kick mage and peel rogue.
Pain supp, barrier, any dmg reduc abilities have more value the higher hp you use them. Trick is not commiting them unless their offensive cds, like dance, are commited.
Vs double melee its all about getting peeled and los whichever has a mortal strike ability, hunter warrior rogue etc. If your partner can say kidney a warrior and you can get around a corner to avoid charge then MS falls off and you can top yourself off even with the other guy on you. Dont let garg pump into you, los, shackle with inner focus up.
Speaking of inner focus use it early and often. 45s cd and enables you to actually heal lol. Your 4set gives your pw shield a freedom, time this vs mages novas so that you can get around corners, if you shield as soon as your out of stunlock or deep use that time to get around a pillar instead of standing there healing. Shield, PoM, renew, holy nova, desperate prayer if u have to while running but get value out of that freedom from shield.
Vs double dps dont bother using mana on damage or dots. Just survive and avoid cc with swdeath. Getting drinks can be tricky, your partner has to create the opportunity most of the time. Any chance you see to drink do it even if its just a tick or two. Once trinkets are down a double fear they have to sit while you top off los, combat drops and you drink.
Someone else mentioned this but yes getting full value out of fiend is important. There are macros to summon+use his shadow step ability whatever its called + dispel so you can summon it and dispel him with the same button. Keep him out of fears / novas. Use it at a good time, warrior fear on cd etc.
Hydramist and Hozitojones have a lot of R1 disc priest content. Even just watching their globals and how they survive scenarios will help a lot on decision making.
Good luck!
