Yet another server I have been on has tracks similar to the ones just inside snowpelts lair but these are placed all over the mod and tell you if a toon that has a bounty on them has passed by and how rescently. (city of Arabel I believe) There are a ton of PvP enhancements.
Used to be here. Everyone left a footprint that lasted for awhile and if your skills were up to par, you would be able to decipher information like race, how long ago, even names if you had enough points. Problem was with everyone leaving foot prints that last a little while, it BOGS the server down tremendously. it was removed and even then the server needed the clean up script implemented to speed things up. On a smaller server, like this was WAY back then... it would be great. For GvM now.... never.
