What comps do the best with Shadow Priests?

My wife has decided to main a shadow priest (formerly was a BM hunter) for Shadowlands. I currently main a DH, but I’m not happy with the changes they made to them recently, so I was thinking of trying a different class. We enjoy 3’s arena together to get mounts, so not sure which class I should roll with that would work best for us? I narrowed down the list of classes I’m willing to give a go, just not sure which one to go for.

DK
Rogue
Warlock
Monk

Unless there’s another class I’m missing that may be even better to use, feel free to mention it. What do you guys think I should roll with that works wonders with Shadow Priest? I would guess Warlock, but open to opinions.

Traditionally might be strong choices for spriest.

Rsham ww spriest* (interchangeable with boomy) plays well, however you kind of need the sham since spriest doesn’t have a reliable kick

I think they have enough strong synergy

RPS was insane on the beta.

I play my ret with a sp friend all the time it feels fine with any healer

prob rogue/lock > monk > dk

This.

Warriors always do well with SPriest.

Warlock is a good pick if you’re going affliction. Rogue is also a great choice since priests aren’t exactly known for their mobility, and a rogue would provide the priest with solid peels.
