Now we all know that one of the biggest set backs of this awesome game is the implementation of energy, which is used in almost everything.
I was thinking that maybe one way that OOO could improve on this, is to allow for the NPC Boost (who is the guy in the picture when you click to buy CE) to sell Mist Tanks, for maybe 10-15k crowns to players. And to reduce the chance of rich players just spamming mist tanks, it could be set to each player only being able to buy 1 and only 1 mist tank, DAILY.
This doesn't help players to craft more items quicker or anything, it simply gives players that option of longer game time. Because like most of the players out there, I hate playing for around 60-90min then having to wait 22 hours for my mist energy to completely refill.
Er... If you have 10K or more to spare, you can just buy 100CE off of the energy market, and run the clockworks using that. Your suggestion would only make sense if 100 CE on the market went above the selling price of those mist tanks.
