I saw this coming long ago. After seeing the news, my expectations are low. Not my first rodeo for xpac launches. Got workarounds planned.

Day 1 (Fri) - Public holiday for me. Launcher and Login system has issues at 5pm (+8 GMT). 3000 queue. Got multiple 2002s. Then I'm able to queue and I got 7000 queue. Watched TV shows and played other games. Waited hours to play it. 2002s are gone though. Did not complain because I expected it.
Day 2 and 3 (Sat/Sun) - Its my off days. Woke up early and play. Only 2 digit queue.
Day 4 (Mon) up to today - Work from home. Turn on PC at 4.55pm. Around 700 queue. Able to play at 5.30-5.40pm when my work ends.
Next week - Work day at office. Will turn on my PC with power savings on before going to work. Using remote desktop to que at 5.25pm (+8 GMT) beating peak hours. Should get about 700-1000 queue. Probably around 100 left when i reach home.

My PC is on wired cable. Less chance of 2002s.
