It's frustrating having to wait so long for energy to complete tasks. It wouldn't be so bad if there were more things to do in the game while you wait, but there aren't. This isn't a game that you'll spend hours on. You wait hours for a few minutes of playtime, especially classes that feel repetitive and take 3.5 hours to finish. According to reviews, it only gets worse as you get further into the game. I wonder how many people quit playing early because of this
