This is a good suggestion, and with all of the discussion around the duty rule, we've been looking for alternatives to 'solve' the rule. However, I'm not sure if this would be a good solution. For example, if the president is new and hasn't played the game before, he probably won't know about these commands, and thus won't be using them. Or if he'd use them, he'd probably just be copying what people are telling him to do. If the president is a regular, I feel it would mostly be used to kick new people out of the security team and replace them by their friends. Both of these examples won't have an effect on enforcing /duty, and on top of that it might deter people from staying, since the security class is one of the more 'attractive' classes, and I think that plays a big role in why people keep coming back.
I think basing it on a point system is a good start, and maybe we should expand on that and link it with incentives and rewards, to encourage people to do their duty, instead of punishing them when they aren't. I'm not sure how exactly we would implement this, but I feel a scoring/rating system together with rewards could possibly be a better solution.
