FWIW, as a player who has often bitched about the Zuma– I'm psyched about them torching Saffalore.
I just wish they would also burn down Aurvandil.
Like I've been saying for maybe a few years now: the Zuma need to burn !@#$ down, like all the time. Not just sit there and play a measured game. Them torching Saffalore added a new entertaining bit to a power struggle and levels the playing field within the former Terranese states. Think of the Zuma as the US and Terran as.... Yugoslavia in 1991.
It bothers me a lot that the Zuma GM functions on a very restrictive information diet, yes. I think they should make lots of public announcements to lots of players, not private messages. The Zuma GM needs to play with a megaphone.
But is there fundamentally a problem with walking in and burning a city down? Nah. I just wish they'd do it more often and more indiscriminately, or else go jump in a volcano.
As long as the Zuma are DOING things in an approximately understandable, public fashion that enables more than just secretive RP-heavy players to interact, they can be cool. That just isn't usually how the Zuma work, AFAIK.
