What an interesting topic, I have never heard of the multiple task list idea, that is very cleaver. I had become very heavy on the idea of having a series of a best of 5, or maybe even as many as 7, where you are allowed to use each splinter including the dragon once, so that decks are forced to be fairly complete to finish quests. Win one series like this-quest completed. Lose two series like this, quest over for the day try again tomorrow. Sounds brutal, but limits time to load for next match already having an opponent, is massively more time efficient, and if you keep winning you keep playing-rather than just having to play several hundred matches each season you engage in these series until you lose two-then go play tournaments, challenge a friend, or perhaps find something else to do rather having to play this 3-5 hours a day to have a shot at being among the highest ranked in the game. Or even better yet, if you must play that much, go lease or buy another account full of top notch cards. If that happened the amount of cards floating around on the market and in the delegation market would vanish in a heartbeat.
