NOTHING IS WRONG WITH CASUAL, ITS TOTALLY FINE AS IS.
-some lyra guy
Of all people I thought you would be the first to jump at a way to enjoy truly casual games.
I side with Lyra in the discussion of the casual game mode but also agree there needs to be a fixed third mode called non-competitve where you can't complete quests and doesn't count to the 10 gold per 3 wins for the record.
OP you put forward a good idea if only there was a way to properly implement it in game lobbies are actually needed at this point with the game as big as it has gotten. Also I honestly believe it is a finacially beneficial idea for blizzard because full meme decks tend to be more expensive so a way to enjoy them would encourage more purchasing to make them.
