Blizzard announced, with those notes, that cross-realm arenas were here. They followed this up with a blog on the subject, so let's take a look at just exactly what the changes entail.
- Arena teams have been removed. All you need to queue for arenas is a party of the appropriate size, so two, three, or five players.
- You can make cross-realm groups to queue for arena, with friends of the same faction from anywhere in your region
- The arena rankings, along with the titles and rewards associated with them, will be region-wide, instead of by battlegroup
- Conquest point cap, MMR, ranking, and overall rating will now be based on you as a player, not on your team.
