Hey now, there's nothing wong having an emotionally disturbed character run amuck now and then, though I conceed that too much of a disasterous thing can get tiring. Too much of anything gets tiring for that matter. Some old school cloak and dagger stuff sounds like it could be intersting.
We used to do road blocks and petty scams a lot. Lots of back biting, back stabbing, tail cropping and a hell of a lot of threatening to cut people's tongues out if they blabbed about things they should have kept to themselves - though it was very rare to actually see someone without a tongue. Swords and daggers were flashed more than actually used. :p
Camp banished was kind of neat I guess, but what I didn't like about it was that it was so remote and guild houses in general, I really dislike - mainly because they tend to physically separate and isolate people. It's hard to get into an RP if you can't find where everyone is. This was in my opinion, one of the advantages to rping in an open space.
Another thing is spying. Spying works great in taverns and such, but when people start using their physical location to guarantee privacy, then the spying kind of goes out the window - unless you can get someone to betray their group.. but that's much more difficult.
I remember when I was new to the Outlaws, I walked into Jayose library and spotted Lhaa standing in the corner of the door and facing the crack as if looking through at the people who were inside the building. I was a newb and sent a /tell to guarantee that nobody could hear what I was saying to her. I asked, wouldn't it be better to just go around the side of the building and listen through the wall? Surprisingly, he said he would rather see Lhaa get caught for being a nosey little bitch than play it super safe. This seemed counter intuitive to me at first, but over time, I saw the wisdom in playing loose like this. Sometimes you need to let things go wrong and fall apart on your character so the game flows and things happen. It doesn't mean you have to do terribly stupid things, but rather just to open up and take some risks. If your character gets caught, they might get bribed or beat up or whatever, but it's just a character, no real damage done.
