1. Stealing is too easy. Either change the difficulty of the stealing itself of lower the price of stolen things. Paiting for example should cost 1/5 of the current price.
2. Somebody already told but when not using lockpicks you should have a chance to destroy item inside. I really dont know how this went unnoticed for the whole beta tests?
3. Dialogs/conversation in Co-op. Already stated in some other topics. At the moment its very annoying.
4. Add Very Hard and Insane difficulties
5. It would be nice to have some kind of book/option especially for crafting. Once you experiment with ingidients and craft something it should be saved and easily recreated.
