In World of Warcraft there are arena fights and there you fight for coveted arena points. Players can choose between different game modes. Arenapoints can only be earned in rated fights and not in practice fights.
You must have reached level 70 to participate in rated arena combat. At the end of a week you will receive Arena Points, how many you get depends on your performance. Blizzard's combat system allows you to always get the same amount of enemies. If the system doesn't quickly find enemies at your level, it will expand the search radius.
You're pretty good and the system will give you worse opponents, so if you succeed you'll get less points than usual, and vice versa if you win against stronger opponents you'll get more points. When you earn Arena Points, you will also be given a weekly limit, once you have achieved this you will not be able to earn more points.
We at Melk Trupp will play the PvP Arena for you and secure the cap for this week.
