Patch 2.4.2 came out today, which is mostly a bug fix. It does, however, have 1 big impact on Arena play. The proposed point changes for Arena Season 4 were implemented today. Specifically:

1. If a character's personal rating is more than 150 points below the team rating, they will earn points based on their personal rating instead of the team rating.
2. If the average personal rating of the players queuing for a game is more than 150 points below the team's rating, the team will be queued against an opponent matching or similar to the average personal rating.

As I mentioned in my previous Arena Season 4 post, this should help reduce point selling quite a bit, and make it easier to play against like talented teams.
