Well, I have been playing this game for quite a long time now and my first impression was really good. You got rares really fast and the arena's where balanced.
After some huge updates the game was getting worser and worser. It was clear to me that the company was out for money. They changed the droprates and they unbalanced the arena. The only way to get fast rares is to pay for it.
This is a short summary of this game. It could be longer but I wont wasting more time. It was, ar first, a really nice game, with a good gameplay experience, but now the game dead. Only the payers can play the game and ofcourse rule it.
