I don't really need to tell you that WoW has been a little rocky since patch 3.0.8 launched. The forums are filled with players who are angry and threatening to cancel their accounts. There are some that think we need to give a Blizz a break.
Snagger of Quel'dorei pointed out that there are risks involved in launching new programming. The PTR cannot quite grasp the effect of millions of users. I've experienced bugs in new software releases in many areas. Everything from the Windows XP security bug in service pack three to software developed for my employer that regularly crashes the computer. We come up with work-arounds and the the developers work to resolve the issue. What we're experiencing is not unique to WoW. If you're missing out on your favorite WoW activity, try something else: run battlegrounds, work on reputation, help some lowbies, roll a healer.
