I wish I shared your confidence, still playing the Test version and not only have we not seen the fixes in action, so we can check they actually work, and don't break other stuff too, but on there even the "fixed" stuff has been bugging out again, the zone refreshes and out of memory issues are now worse than when there was activity on the server, during the live event the server load has been almost zero there.
Even more worrying is the database corruption issue that's been locking people out of their accounts, if that goes live then the you know what is really going to hit the fan.
