Blizzard Poster Tyren has announced that this coming Sunday, 12pm to 3pm, Blizzard will be holding a Worldwide Arena Battle on the Tournament Test Realm in order to focus testing on the server. Members of the community and development teams will be queuing up to fight, so if you've always wanted to show Kalgan or Tigole what for in the Arena, this looks like your chance. You can expect a battle between the various CMs as well, so we'll have to watch to see who gets stickied and who gets banned.
If you're not sure how to access the TTR, you can read Zach Yonzon's guide here on the site. Don't worry if you don't have a character transfer slot left, every character created on the TTR is automatically level 70, and will spawn next to a selection of vendors that will let them buy a wide variety of gear to outfit themselves for battle.
Assuming the TTR doesn't collapse under the stress, we'll see you there!
