I'm arena 17 and right now am not happy with the game. My biggest issue is the Teleport dice. The problem is, if you have a few of it it just stopps spawning mobs for the enemies since the monsters your opponent receives relate to how many you slay. This makes this build rediculus since the enemies can't build their board and when the boss wave arrives they receive 50 monster at once. The latter would be already strong but the first part is game breaking unless you play assassin/insane waveclear
