I just made some slight changes to some parameters in the game right now; they are mainly aimed at slowing down the altpocalypse we're seeing right now.
First of all, the walls were made a lot tougher: I doubled their damage soak value (aka armor) and quintupled their health. The brickwall was also made quite a bit more expensive [but don't worry, it'll be worth it ;)], and the palisade was made a tiny bit more expensive. They need to be repaired to reach their new maximum health level, though.
Second, I made the black skills an order of magnitude more expensive. This one is just a placeholder until we get some real system for making the acquisition of skills harder, but at least it should be a little less trivial to create new throw-away alts for thieving. It might, on the other hand, just be an invitation for macroing. Again, it's just a place-holder.
