Become One With All Things
This is a no from me, because it's just focusing effort on the wrong parts. Focus first on what keeps the big juggernauts insulated, and this will look a lot more appealing in that future.
The only means of forcing factions to not be insulated on the board right now is invasions. If there was another means to do so, I'd be down, but I don't like the idea of policing who people can or can't write with. It's a hobby. If CIS, TSE, and SJC want to just write among their writers 90% of the time, and the other 10% of the time for them is when they willfully reach out to do invasions? That's not great for most of the board.
I see what you're saying, but what is a reasonable means of deciding how to keep these factions from being insular? Cause as I said, the board has a mechanic for it right now and it is one of the greatest ways to increase activity for all factions involved as well.
