Could the disagreement encompass the difference between "Everyone can attend, very small subset can participate" versus "Everyone can attend and participate"?
Nope, it cannot. Not unless you can tell me how a Noble could participate in this that a commoner could not.
For sure, there are events where the governments have more to do than the rest of the players, but this wasn't one of them. For this specific event, it wasn't any less boring for us Nobles. The only difference between me and Subo was that I went in expecting nothing more than this, and possibly that I enjoy this kind of RP-talky event more than he does (which is probably why I became a Noble).
I agree that this event was only for the small subset of people who are interested in witnessing what's nothing more than a bit of talking to set the mood for a later event, and that that probably should've been made clear in advance, but it was not by any means only for Matis/Nobles to participate in.
