As I've posted in another thread about the server crashes these issues happen every time there is new content. Every major patch we get we also get what I like to call the 'temp players' that come back to playing the game for the new content. The temp players are a large portion to why the servers crash like they do after we get the new content, then there are other issues that contribute to the crash problem like bugs that need to get ironed out. With this patch and the new cross world party finder that is another feature that would contribute to the data center crashes, give it some time for them to iron out the bugs. Another thing they could do is put the brackets back in like they did when he was released until things smooth out again and the temp players get their full of the new content and disappear again.
