I hate dim shields.
(And no, I have decks which beat them to the ground, it's just that mono aethers are the only decks in (bronze/silver-) arena which leave no chance of winning when playing with some specific decks.)I hate grinding with the same deck the whole time.
I hate the inability to get shards without arena/pvp. (Cause of my sometimes really poor internet connection)
I hate the fact that 1.4 still takes a damn lot of time and testing till it's finished (because it will finally remove the problem above...)
I hate newbies which only register on the forum to complain and telling us that they will quit the game, instead of looking for help with their decks/strategies.
Well, I guess it's better to complain in this thread than somewhere else
