I would keep summoning their ass behind the locked door in Galadon.
I would also likely find a way to flag the people who would come to aid them.
In other words what thebigc is saying is that tribunal anything, but especially tribunal AP (and imho duo'd no guards tribunal transmuter) is just an excuse to be a giant cock.
If they were forced to fight the flagged people in town to the point that they couldn't hide in Guilds (but could hide in the Spire, go for it, it's a cabal.) then you would have a much different story for who would choose to be tribunal for powergaming and who wouldn't.
