Too grindy, what I hate about freemium games is that their enjoyability depends on either an absurd patience or a bunch of microtransactions. I'd rather we could just pay a fee for downloading and playing without having to worry about anything else.
Is it bad that I don't mind grinding for some prestige to speed things up? The balance feels just fine with me right now. Seems like I'm patient player.
You know, many MMOs make money just fine without an energy system. For this game to reach its full potential, that "freemium" feeling really needs to go.
