Today and tomorrow we're going to start testing some 25 player Normal Difficulty bosses. Note that there will be additional testing opportunities for both 10 and 25 after Blizzcon.

13:30 PDT - Yor'sahj the Unsleeping (25 Player)
15:30 PDT - Ultraxion (25 Player)

10:15 PDT – Morchok (25 Player)
13:30 PDT – Hagara (25 Player)

As always, the scheduling for PTR testing will be VERY fluid. Tests can be announced, canceled, or rescheduled at a moment's notice depending on build and server status, outstanding bugs, etc. I will try to give as much advance notice about tests, but that is not always possible. Also note that these encounters are all works in progress.
