I think this game need a new sistem of energy trading, because if a player is tier 1, he need someone that sells energy and are in tier 1. Example, 100 energy for a player are in 1 tier, is much lower than the price of a tier 2 energy. If you complete the floors 1-8 you can get +- 3k of crowns, a 3* equipment need 200 energy, a full day without playing and 7k of crowns. I think a full 5* equipment, can easy do the last flowers and make much more than 7k crowns and buy energy how much it wants.
