For our struggle to cope with the new energy mechanic in DL I have thought of a way to help. STS should make a 5 star vampire hotel that costs about 30000 gold for a 3 day stay. While you are a guest at the hotel that cuts the cuts the energy time by a fourth. Also for those three days in the hotel you can go in the pool that cuts the energy wait time in half. Also you can go to a casino that is full of fun card games and other mini games.
P.S. I personally like the energy mechanic, it gives an extra view on how to save or use energy for a max amount of XP.
