Question: how do arena points work in wotlk?
Answer: 3v3 teams earn 88% of the points of a 5v5 team with the same rating. As of Season 6 and later, the arena system was changed so that new teams start with a rating of 0 rather than 1500. Consequently, the formula was changed so that all teams below 1500 rating will earn points as if they were a 1500 rated team.
