Also, what they need to do is totally rework the ladder system. Plain and simple, quick wins ladder you the fastest. What this means is that the game strongly, whether directly or indirectly, promotes fast, aggressive decks. People playing control decks are actually playing counter-intuitively, if they're trying to ladder with them.
At the end of the day, ladder needs to have an "exp" system, whereby you gain experience which then translates into rank. The experience can be based on any number of factors; however, a person playing slow deck X for 2 hours a day and playing 10 matches in that time with a 60% win rate should have the same rank as another playing fast deck Y for the same amount of time, playing 30 matches and having the same win rate.
It's supposed to be a fun game. Don't penalize me for not wanting to play some brainless, garbage, keyboard-faceroll deck.
Also, they need a tournament mode, a-fucking-sap.
