I find the only existing RP cabal to be the Heralds.
But Heralds are quite limited in their RP, as they need to be Heralds.
What If we had an Umbrella CABAL, lets call it Society.
This cabal would be the top RP cabal. Then we would have subdivisions cabals like:
Heralds, Academicians, Merchants, Noble, Royal.
All in the neatly organized in the same cabal, but still individually tailored.
This ways some powers would not cross over.
There are many nobles this days, and little reason for them to be Heralds. There should be a Noble thing (better than Faction). But still interconnected to all RP things in order to promote interaction.
Mya, why reinvinte the wheel..
Those things are all in the game.
I seriously don't get her sometimes 
Finally an idea from Mya that I kinda like. Don't see a real need for it but I like it in principle
:-P all of those things exist except lumping them together. It is technically just a cosmetic change. It MIGHT help stimulate RP but I doubt it.
Now had she been a true politician, she would have slid her combat smoking ban into the fine print. But, I happen to be on her side in this one. Atleast to a point, I do think there needs to be seperation between the nobles who seem to always be involved in shaping history, and the Heralds whose job is suposed to merely be recording it. It is an age old issue that is due some attention. Out of respect I will leave any examples out of this post, but those who know, Know. So instead of attacking Mya, lets shape her lump of clay into a sculpture we all enjoy looking at.
Mya, why reinvinte the wheel..
Those things are all in the game.
There are alot of things in game that could be tweaked to be made better.
I am all for ideas to get more RP rolling.
Lay-About and Tetsunai. Those two do nothing but kill me, i swear!
