The devs have been working on the matchmaking code and will be holding a three hour-long test between 2-5pm Pacific Time on Wednesday, May 21, in the Beta server battlegrounds.

We will be having focused testing for the Battlegrounds Matchmaker on Beta tomorrow from 2PM – 5PM PDT.

Along with those Matchmaker fixes, the following adjustments have been made to itemization.

• You will no longer need to add a gem to your PvP gear before upgrading it to the next tier.
• Toughness has been reduced on one gemmed Dreadnaught armor, all other blue and green stats have increased to 3 gem potent quality.

Players who participate will be eligible for some nifty rewards.

To copy your character to Beta, simply type /beta from the character you wish to have transferred over.
