Double maximum energy cap. (1 per week , 100 -250 points?)
2nd energy refill per day (Pay 50 points for 2nd refill)
2nd nerve refill per day (Pay 50 points for 2nd refill)
Token Shop Items for points - backgrounds, hairstyles, honor bars (I honestly have no idea what to charge for these)
I think double maximum energy cap would be sought after but because it isn't an increase in energy as such, players would still have to stack in the normal way, using Xanax etc., so it doesn't have a negative effect on the economy. This would be sought after for ranked wars and special events, such as Halloween and Valentines Day. Possibly, you could charge more.
Not everyone would be interested in nerve and energy refills, but I think there would be some interest in a second daily refill.
As there are less and less events now that award tokens, it might be a good time to offer an exchange of points for tokens or a direct purchase for points for token shop items. The honor bars don't need to be the same as the ones available now if they are event specific. Maybe phase those out and create some new honors for points.
