thats fair but what i think people need to remember is that disc is likely impossible to balance. in 5 mans it's pretty fucking strong simply because dominate mind exists (and makes disc priests able to reach 300-400k dps easily). obviously you don't have access to dominate mind in raids, so you're losing about 50-66% of that 300-400k dps immediately. now you're sitting on 100-150k dps max, but you can never achieve it because it requires hitting penance on cd... something you likely aren't going to do because you need to save penance for big bursts of damage. so you save penance, making your damage bad. now your atonements are much worse off, so it makes PWR (which is pretty op) seem a lot less powerful because for it's cost it cannot be justified. idk i just don't think the spec works.
it honestly feels like you'll be forced into SM/SC spam ... in which case just play holy priest/resto shaman cus those specs bring much more to a raid. right now i think the strongest specs are shaman hpriest monk (in that order). they're all hps spammers and do something for the raid. i would hope im not wrong because i would absolutely love to see holy priests be the dominant spec again, but at least this expac it seems like disc players will need more than mashing their face into the keyboard to do well
