New test realm patch notes.

...you aren't seriously suggesting Blizzard's internal testing department is up to the task of discovering all PvE bugs and issues themselves, are you?  :whistling:

Blizzards ability to successfully do internal testing isn't the issue. What is the issue is project management and how testing is done in these types of games for different features. Seriously, how many people does it take to successfully test a PvE quest? 10? 20? 40 at the most, theoretically, as that is the highest amount of people that can group together. Get them together and do the quest. Does this step of the quest work? Yes, move on. If: No, send bug back to developers. The only thing that additional levels of attention on that same issue will bring out is whether there are uncommon character/item interactions that break the same content that under normal circumstances works. As such there isn't any need for multiple servers to test this type of content.

PvP however is the complete opposite. Everything about PvP interactions falls in the margins. Thus you need every possible person out there casting spells and mixing abilities to find the places that don't work properly

As someone that has spent a lot of time doing testing on both MMO's and console games the fact that this game is out and as successful as it is alone tells me that Blizzard is quite capable of doing internal testing.
