SO MUCH THIS. I would play Legendary so much more if it didn't do this. Life gets in the way of a lot of my game time, it would be so good to be able to pause the game and come back to it shortly.
And while we're on the subject, why does a solo game even need a turn timer? And why can't I select which hero decks are being shuffled into the main hero deck at the start? (Maybe I'll make a new thread about that though)
