WoW Cataclysm introduces numerous new changes to the Pvp systems, including a new zone dedicated to world PvP, new battlegrounds, new arena locations, rated battlegrounds and many new rewards.
New PvP Point SystemHonor pointsThese are the lower-tier PvP points, and will be gained from most PvP activities. There will be a maximum amount a player can have, but no cap on how quickly they can be earned. Conquest pointsThese are the higher-tier PvP points, and will be awarded from rated battlegrounds and arenas. There will be a cap on both the amount owned as well as how quickly they can be earned. With the Conquest points being obtainable through rated battlegrounds, it will be possible to gain high-end PvP gear without setting foot into arenas. Most PvP items will have their personal rating requirement removed. Also, there will be a way to convert Honor points into Hero points (and vice-versa), though not at a 1:1 ratio. |
