I, too, find it restraining and odd RP-wise that public places like major cities are the most dangerous places in the mud. The easiness of finding you far outweighs any protection you may get from guildguards or trib players there. It is also more noticeable with low playerbase because tribs are often not around.

Of course, I have a perfect solution. I'll play a trib myself and make the cities safe. Muhahaha!
