Do you still believe that launches of new games and expansions could be smooth and without problems? It seems that that is not going to happen soon. Because even Blizzard has big problems with Draenor expansion.
Currently you must wait in queues, be patient because some guys made DDoS attacks, get over the Garrison bugs and other annoyances.
Blizzard is working hard on hotfixes however for now all players must be patient…
