I really hate whenever I try to explain how some bad rules can be abused and immediatelly get someone say shit like "If this happens in your group, change it" as if that would solve the problem. And whenever it is not soemthing you witnessed personally, then it means it never happens and could never happen.
What are you even on about? If there's a flaw in the system, the best that can be done is make it clear to the group that we shouldn't abuse this, and hope the official rules are changed at some point.
