Earning PvP rewards in World of Warcraft Combat go to the Battlegrounds. There you will be rewarded Marks of Honor for competing in and finishing battles. You still earn 3 marks for a win, 1 for a loss. However, the Brigadier Generals in the war rooms are gone, so you no longer redeem Marks of Honor for cash and extra points.
Find the PvP rewards vendors. These folks are located in the major cities and near the entrances to the battlegrounds themselves (in Refuge Point, Arathi Highlands, the Alterac Mountains and so on). Now, instead of requiring a rank, a certain reputation with a faction and World of Warcraft gold, PvP rewards are earned through honor points. As you earn these, spend them like WOW money at the reward vendors.
Because there is a set limit to the number of honor points which is currently set at around 90,000, so spend your honor points and Marks of Honor. It is in your interest to spend the points before you hit the limit, otherwise you will just be wasting your time in a battleground.
Fight and heal. Honor is awarded for both killing enemies and healing allies. What you should notice is that the new scoreboard in the battlegrounds that tracks both damage dealt and damage healed.
Pay attention to the fine print. As before, the epic weapons and armor available for PvP have level requirements. As a level 58, you'll find it difficult to spend WOW gold and purchase the High Warlord's weapons. If you want to reach a higher level, you can buy WOW power leveling service.
You have to play all the battlegrounds. In an effort to encourage high-level players to visit battlegrounds besides Alterac Valley, Blizzard has assigned the required Marks of Honor for epic weapons and armor to Warsong Gulch and Arathi Basin. You thought you'd never have to go back, but you must if you want that epic gear.
Sit back and relax. Honor will not decay if you don't visit a battleground every week. Once you earn honor, it's yours until you spend it like WOW money. Honor tallies are updated nightly.
