This game has turned into a disaster. Gold used to be a problem, not so much any more it seems earning Gold to level heros isn't as bad as it used to be. What is a problem is Training modules! Getting modules is a nightmare and slows down hero progression big time, and the more heros they add the harder it is to level them up. Also this game is super expensive to play, if you're a free to play player, forgettabout it!' Level 16 mats are hard or to expensive to come by.
