I would rather be for stripping cabals out of the game, leaving tribunals and forming new classes.
However, with the limited brain crunching capacity and idling and hoarding and elite whining abilities of someone like Dark-Avenger we'd never have the chance to improve the mud.
I have no qualms with the ideas of spies from a cabal going into a tribunal and [REDACTED] some things up. It's roleplay, don't be afraid of it. As for oaths to a god, they only care about their followers. I actually never made any character take oaths when joining the cabal I had power over. Either I liked the guy and inducted him or turned him away. If he decided to be an idiot while in the cabal I surely knew how to use cabal uninduct. And personally I don't think a cabal leader has any business making an oath that says you pledge such and such loyalties to such and such gods. The help files don't even support that kind of "guidance", and neither do I. You don't have to hamstring RP because you don't have the capacity to do anything of the sort.
And historically, the Oathbreaker flag was introduced to make it so Peso could only join 1 cabal or tribunal with any given character.
