What is Player versus Player (PvP) Rating?
Player Versus Player Rating is a feature that ranks all players who participate in PvP combat. This rating is specifically used by the Jedi Force Rank System to calculate amounts of Force Rank Experience generated any time a Jedi kills an opponent. All Players will be ranked through this new system. At any time, you can check a player's PvP Rating by typing /showPvPRating. The higher this number is, the more adept the opponent is at PvP combat. Any time a player is victorious in PvP, their rating may increase. However, if a player is not so successful in a PvP encounter, their rating may drop. If multiple players contribute to a kill, their PvP ratings will be increased based off of the damage dealt to the victim by each player. Gaining PvP rating and Force Rank Experience is the key to Ranked Jedi Knight progression.
This was a feature of Publish 9 that was removed about a month later, because Jedi abused the hell out of it by killing Alts on top of their PA Halls to accelerate the raising of their Force Ranking. After Force Rank was removed, PVPers killed alts to inflate their Rating for bragging rights. I'm still giving thought to giving a Trader a 1700+ ranking just to belittle and grief PVPers.
