Testing so far on the Ruby Sanctum has gone well. For the next phase of the testing, we're going to allow raids to switch difficulty to Heroic.

Heroic mode testing will only be available for a limited time, but we hope to allow Normal mode testing for a longer period.

US Testing Schedule:
Thursday, May 27 at 19:00 EDT.

EU Testing Schedule:
Friday, May 28 starting at 19:30 CEST.

This schedule could change without much warning due to PTR downtime, new builds being deployed, etc.
