as spriest / healer you can’t win warrior / monks comps if they’re equally as good as you, they can even throw the game and still win. you can win warr/hpala, warr/disc but def not warr/rshaman.
against RMs you have to play offensively and keep them in combat while your priest is being outplayed by slows, it’s definitely a winnable match-up but your priest has to be really good on the small windows he’ll have to deal some damage
I wrote a post on the priests board regarding how to spriest in 2s a couple of weeks ago, I played a couple of games recently as spriest / rshaman (I usually play spriest / hpala) and it’s still valid : 2s Shadowpriest comps that works and how to play? - #5 by Chlodovechus-khaz-modan
I’m not queuing really high right now (around 2-2.1) but those tips along the other one offered in the thread should help you understand how to play the comp, even if you’ll have to adapt your setups since you’re a druid, and that hpala is miles better.
