One of the issues is that many in the community saw points as meaning serious which of course can't be fun. However, the system is not really a zero sum scenario wherein one teams gains and the one loses but instead a scenario in which one team gains and the other stays the same. In other words, don't only agree to scrims after you have assured victory, have some fun and the worst case scenario is you are no different having played than having not played.
Regarding events, I don't think any event, be it a Muse event otherwise, is automatically counted unless a Screenshot is sent in. From my understanding screenshots could've just been sent in from events like the SR and the AC and anything thrown together as long as the event meets the guidelines.
Its a pretty laid back system really.
