The tailoring display bug should be fixed in the next content patch:

Some issues cannot be hotfixed, I'm afraid; that's not how the system works. We are working on the problem and should have a fix for you in the next patch.

Battlegrounds are coming soon! Could the test servers be going live with battlegrounds this week?

We're happy to announce that we are now just a few days away from being able to deploy the first round of public test realms for our international audience. Due to the need to conduct as much testing of our initial Battlegrounds content as we can, the schedule calls for the next major content patch to go live on the US public test realms shortly. We will then roll out the public test realms for Korea and Europe as soon as the hardware setup and configurations are completed.

We're excited to see players from around the world on the test realms in the days ahead, and we look forward to hearing your thoughts on the new PvP Battlegrounds content!
