Its the same issue with almost every "idle" game at this point. They have very solid systems in place, but the balance is beyond broken. Its not satisfying at all. If the intention is to get people to play online non stop for 40 hours straight each session, sure, this game would be the top. But thats not what the players want.
It just needs A LOT of balance work. Speeding almost every single aspect up by double... It'd still be quite a slow game. Its just painfully slow, thats it.
