They should make the Quest's final reward are not so powerful that makes everyone tries to build decks around the final reward..... i'd rather see the option to include the quest in the deck to accommodate deck building strategies or to help mid-game with the middle rewards.
They should get rid of rewarding "Rest of the game" effect, which are Mage - Shaman - Warlock - DH Exceptions are Warrior - Paladin, their final rewards are something that we can interact with, allow board presence, and don't involve mana cheating.
Other quests without that effect seem more balanced: Druid - Priest - Rogue

No, only popular aggro decks around are Face Hunter and maybe Shaman.. They only rise because they are meant to stop those Questlines from dominating.
Also, the existence of these fast Questlines stop Control decks, which help the Aggro decks to rise.
We have not seen how Control decks will do in this meta without these Questlines' existence
