Just saw that by hassling facebook friends your cards get ridiculously better, you also hinder the campaign by forcing people to buy energy and packs to progress. You sir suck at life and I bid you a 1/5 for your terrible ways.
For all the abuse this game gets... i have now completed it yet here i am still waiting for the energy to refill. There is something about watching that little blue bar go up... :P
@Pineapple12 the people playing the game matter the most and if nobody likes the energy system then the more they bash it hopefully the more notice the designer will take notice. Constructive criticism!
