I have the same feeling. I'm seriously considering selling everything but my main deck (which would mean a level 1 alpha deck, a level 3 deck, 2 level 4 decks and a deck with gold foils.)
I don't have the feeling the game is going into the right direction, so better jump off ship before it is too late.
It's hard to make the decision, though. I've been going back and forth about it...
