The game has always been very pay to win, but it was somewhat balanced by the luck factors. Recently more and more Heroes, equipment and cards that are almost impossible for most people to get without paying money. It's saving grace was the co-op mode which is why I have been playing for a very long time. Now they have replaced the co-op with dungeons which you can only play up to 5 times a day. I hope something is done to restore the old co-op otherwise I will be quitting soon.
