Persuasion needs to be made more clear in its implementation; I have played co-op with several different groups and they have all come to wildly different conclusions (only stats matter, only persuasion matters, every option is valid, some options are impossible, etc). Making it clear that Persuasion involves reading comprehension and that there may be options that will not succeed is important for not confusing and frustrating newer players; especially when it was such a stark change from the first game's system.
