@Bloodyhog13, being level 400 in 1 day is far worse. It takes away the challenge. With infinite energy you can just farm zones until you obtain the best cards and that takes all the fun out of it. The energy system in this game is a must have feature and doesn't detract from playing at all.
@Dragonlx, If you had actually read the storyline, you would know this game isn't about dragons at all. The two clashing dragons represent a struggle between two families vying for control of West Kruna
The packs aren't so expensive considering we are given free dc through idols, coins and levelling for nothing. Also, just buy the packs during the sales and only purchase dc when the cheaper conversion rate event occurs.
