I used to like this game... But for how long it has been out, it should have more content than what it offers. I spent money on the game to help support the developers and I got about 60 summons worth of the red crystals (only way to unlock mythical during the event). I received 1 mythical, about 10 legendary (only 1 was a new monster, the rest I already had), and the rest were rare monsters.. OUT OF 60 SUMMONS! Knowing this, it is fact that the summoning feature is rigged to get you to buy more
