After finishing home island and defeating bandits we should find adventures in tavern. Tavern would be place where we can find adventures at some price(gold, maps, food, material, gems etc.) and this adventures MUST be in in SEQUENCE, to skip replaying adventures. If you want to play again you can buy it from the shop, like now. All adventures do not have to be defeating bandits, they can be contracting type, where you need to build something and in return we can get apart from material, army, buffs and special buildings (but in more percentage than now). After every adventure our exp. will grow and will be able to get more heavier adventures.
I hope you understand what I was trying to tell.
