Game IS balanced. If you start level you should prepare food accordingly what you need. (food gives huge bonuses). EVERY hero has food slot. You can combine lots of foods (for example 5x30 food gives lots of additional hp). Also you can buy potions and other stuff. Cards are also more or less balanced. Some combos work better than others (for example dmg over time cards sucks, healing of yellow heros sucks). If you bitch about ingridients pick druid and you will be overflowed with them. Lots people bitch about game because there are more subtle tactics than in other games. Although game is not easy and is quite difficult. You need to grind on equipment/food/cards. you cant go on without grind.
