Many people complained about gems. Yes, I very understand you need money to make updates for this game, but after your wallet full of money what have you give for us? I just see the boring invasion everyday, no chance for us (non gemmed player) to win the invasion. No updates, no fun, just boredom.
Waiting is boring, how about making a mini game? While waiting the energy to refill you can also play the mini game and you can get a small amount of money and experience from that.
Yes, many people had complained about mist potions. Maybe the price is too high, But if the price staying at the same price I can easily get 52 energy and the get millions coins and do it over and over again. This game will have no challenge.
Well Darth, you are right, but, who want to spend energy for changing a town? Sometimes you will need to move from demon gate to another town to get fairy dust, and you will do it several times until you kill the boss. But if it was orb gate, how many energy would you spend since the boss have 10 million HP ?
