It's over already? hmm
15 years ago servers with 2GB of Ram handled these events , and now when we can have 50 times faster hardware , they struggle with performance. Population per server is not 50 times more than we had. Game not changed at all.
you've probably never been there in vanilla. aq opening was one of the worst lag fests back then. It was simply lunatic. They do all the tests to make it a better experience this time.
and after all stress tests and stuff thea do the game will still crash ppl will cry on forums and the cycle of living continues thea will test and we will cry :D
