First of all this game in my opinion should have stayed on facebook in its current state, i don't know how many times i've lost arena duels because my opponent's LP and monsters have been 2x or 3x that of my own, as for the energy consumption rate come on! This is kongregate! I for one don't like having to stop playing a game because i've run out of energy and coins for the day. Add more cards, fix the energy consumption, and balance the arena then it'll be a great game!
