I think this could be something they could do to keep Hearthstone fans interested and make the game refreshing.
I don't know much about WOW lore so these probably won't make sense, for example:
Mage: If you have spells of only one spell school in your deck your spells gain an additional effect exclusive to that spell school
Priest: Exclusive cards for Shadow priest only, Exclusive cards for Holy Priest only
Druid: Hero power evolves over the course of the game

Perhaps they could add Chi as an additional resource, like DK with Corpses.
You meant deckbuilding restriction like DK rune system ?
Because, Some already have unique mechanics already,
Demon Hunter - Outcast
Druid - Choose one
Paladin - Silver Hands
Rogue - Combo
Shaman - Overload + Totems(maybe)
Warlock - Discard + self damage
They added Overheal to Priest lately, maybe they add more to other classes aswell.
I don't know why but Enrage was fitting Warrior a lot, I still can't get why they removed it. They removed it with the release of Frenzy keyword iirc. Maybe they thought playerbase would be stupid enough to be confused similarities.. Yeah, they always act like as if we are stupids..
