The Arenas of World of Warcraft give the most battle-hardened
and cold-blooded fighters a place to compete against each other in
gladiatorial battles for honor, glory, and power. Gather your allies,
build your teams, and prepare to face off against formidable,
merciless opponents in a race to claim the honor of being the
highest ranked Arena Team on your realm.
  The main goal of the Arena PvP System is to offer players a highly
competitive environment that does not rely so much on a huge
investment of time but rather on a team's playing skills. Because the
Arena System is meant to be the ultimate PvP challenge, the level
requirement to join an Arena Team is level 70.
  At the end of each week, your Team Rating is used to calculate how
many
  Arena Points your team will receive for this week. Your team needs to
have fought a minimum of ten matches per week to be rewarded with
Arena Points, and a player must have been in at least 30% of all your
matches to be eligible for that week's points. The transformation from
your
  Team Rating to Arena Points starts off as a linear function, but once
you go beyond a certain rating threshold, the function becomes
logistic. This means that you will see a significant payoff increase
once your Team Rating goes beyond a certain point, but the high-end
spectrum of the ratings will eventually notice a decrease in how much
bang they get for their buck.
  Rewards of arena Leveling Arena Rewards include both class-specific
armor sets and a selection of unique weapons, off-hands and relics. All
  Arena Rewards cost only Arena Points to obtain.
