WoW stands for World of Warcraft is a game where players have the option of fighting against each other in a variety of settings. These options include beach games, a small map where two teams face each other on the battlefield. There are three sizes Arena game is a 2v2 (two players against two players), 3v3 and 5v5. Here is a rating system, while players with less "skill" is placed at the lower levels, players more often around 1100, and qualified, around 2000 rankings. The more you earn, the higher rank you get. If you win against a team that is much higher rating than that, you get more votes. Arena only purpose is to eliminate the opposing team where the team managed to do, win.
Type rating also applies to rated battlegrounds where players face each other in battles 10v10 or 15v15 on the map Battlefield normal. Rated battlegrounds group, or team, often have a leader or a few who will tell you what to do during the game. You have to listen to them, otherwise you can only kick you out! Even if you are new to the game, or just PvP, then I can recommend starting with a common battlefield.
Regular battlefields are often made up of leechers and less motivated players are good for exercise, but often you will be close to no competition at all, or is too much competition. The game is balanced in the normal battlegrounds are fairly rare, often a team has a team of better or more skilled than others.
Battlegrounds always has a purpose. This objective could be to take the enemy's flag from their base and capture in itself and in Warsong Gulch (WSG), or TP (Twin Peaks), could be to capture and hold the bases as the Eye of Storm and Arathi Basin, and even kill the last boss of the enemy base, as in Alterac Valley or the Isle of Conquest. Purposes even mix with each other in several battleground as Eye of the Storm.
The best defense is a good offense, which also applies to PvP in World of Warcraft. Although there are statistics like strength and endurance to match the enemy, and survived. You should always be active in one form or another, you should not wander aimlessly. If DPSer, keep doing damage or Crowd Control (Polymorph, Blind, Frost Shock, etc..) If you're healer is to heal a target that is low on HP or CC as many enemies as possible. No matter where you are PvP, you should always have something to do.
If you're dying, go defensive, use all his defensive skills and trying to get out of line of sight of the enemy, and ran to a healer on your team (s). If you do not have the defensive skills ready, use all your offensive skills - because as I said before, the best defense is a good offense. If you are able to do more damage to enemies who attack you instead of him for you, then you beat him, unless he has the defensive capabilities more than you.
