You know, allowing us to edit our taunts in the lobby was a nice idea. But here's the thing: the moment we are waiting the most is not before, but AFTER going to character and card selection. And at that moment, that feature is unavailable even though it is the moment when we'd like to use it. To seasoned players, this is pretty much the moment when we are always waiting, doing nothing, and it's frustrating to see the taunt edition feature greyed out.
Please allow us to make use of our time that way at that moment when it can take minutes for newer players/friends to fiddle with their decks.
