First, give up all hope here. This place and the hearthstone reddit are stuffed full of fanboys who would kiss Blizzards butt for a bag of crap.
Second, welcome to hearthstone. Priest has been the cancer of this game for the majority of the time. Even when it sucked, it always could highroll some annoying setup that you just lose to. Between res priest, it’s various TKO with inner fire, and other nonsense, priest is the worst class in this game. It’s normally inconsistent, it’s miserable to play against, and usually cheap when you lose to it. Couldn’t keep 100% taunt and predict if they have one of 10 best in game removals? Die. Can’t keep their cancerous board clear 100% of the time? Die. Can’t polymorph their BS cards so they get resurrected 50 times? Die again. I wish demon hunter outright replaced it.
