priest legit used to be my favorite class before year of the pheonix. They butchered the class so badly. You used to have like 4 different ways to play priest: uber control, combo, and "play a beefy minion early on and buff it with spells and use your hero power to keep it alive all game/divine spirit/inner fire" and "big priest" which sucked and should never exist in hearthstone ever again.
Class worked great and rewarded creativity. Instead they felt the need to "redesign" the class by simply removing the other 2 ways you can play the class and leaving control as your only option. Then they buffed cards like Shadow Word Death for absolutely no reason to further incentivise you to play that 1 specific style. Such a shame man. I loved the quest deck in uldum too. One of my all time favorite decks as well as odd priest in the year of the raven.
