We will soon begin public testing of patch 5.0.1 of World of Warcraft, a patch that will precede the Mists of Pandaria release, and includes many features and functions that are new to the game.

We encourage all players who wish to test patch 5.0.1 with us to take careful note of the following:

• It will not be possible to access the 5.0.1 PTR realms with a game account that accesses the Mists of Pandaria Beta.
• If a game account has been flagged with a Mists of Pandaria Beta license, it can only be used to enter Beta realms.
• This limitation is on each World of Warcraft license, and is not Battle.net account-based.
• While testing 5.0.1, players will not be able to access zones or content that is a part of the Mists of Pandaria expansion.

Thank you for your continued support of our testing and tuning process. We look forward to seeing you in-game.

Scenario Rewards are Not Impressive
Rewards for scenarios are not complete. You should see a grab bag with a chance for a random dungeon quality blue coming soon. (Source)

Alliance Kites are faster than Horde Kites
You most likely saw another player with the new guild perk "Ride Like the Wind". It increases flight path speed by 25%.

New Scenario Available for testing!
We just enabled the Crypt of Forgotten Kings on the beta realms and we are anxious to get your feedback on it! A new sticky thread is here for your posts.

We also made individual sticky's for each of the three existing scenarios on the beta. Please post your comments to these specific threads, it really helps us sort though the feedback faster.

Monk
Spinning Crane Kick Chi
So why is it that 3 friendly targets being healed by SCK doesn't generate 1 Chi as well?
It will. (Source)
