If I'm a Rager, I want tribs around because then I know exactly where they are going to be and when so I can waltz in and kill them. Particularly if I have deathblow, bloodthirst and/or am a bard.
Outtie RP I never find very interesting for all of the pseudo-masochism you need to go through in not using coins and not being able to force barter-only shoppies to give you more shit. I never have problems with Outlanders outside of ranking and many times not even then if I avoid AP's/necros/dwarves/duergar/conjies which isn't that hard because most of those with the exception of duergar are shitty ranking partners for evils.
I detest cabals whose only existence is to grief other players in combat or philosophy and Tribunal serves to do exactly that, prevent PK cause exp holes, harrass you with overpowered manacles and perma-hasted guards.
Of course playing classes that can separate people from the guards that are pretty helpless without them is damn fun. But I have problems with their purpose in the game and the way they do things that will never be resolved. I only just recently got over Empire when they turned back to gold only, but I'm pretty sure I could find an excuse to full loot people as an Imperial just reading the 'getting copper' guide I put up.
