List your preperation things for Shadowlands.
Will u pack up on snacks and drinks?
Will u sleep a ton before launch?
How long will u play during launch?
Will u take days off work to play?
List anything that has to do with preperation for the new expansion! 
edit: yes, this is a massive nerd topic
Step one : clean bank and bags !
Step two : hmm,there is no step two i guess 
Unlock Allied races
I don’t ask my job for day off for this or try fake sick. Sicne I feel it’s stupid.
So I don’t busy for this. I can peace at home after job.
Step 1: Decide on main 4 characters
Step 2: Test classes of said characters in beta
Step 3: Get upset over changes and go back to Step 1.
Eventual Step 4: Make all the characters.
Step 5: Delete all the characters
Step 6: Swear to focus on main and decide on other 3 later
Step 7: Get bored out of my mind and make all the characters. Go back to step 5 and repeat until pre-patch.
Sleeping a lot a day before launch, waking around 6 pm!
Cleaning the room so it’s clean and nice!
Going to the store getting snacks and drinks!
Ordering pizza and pasta! Getting my bfs laptop on the table so we play together.
And enjoy the whole night 
Mine usually consists of buying a ton of bottled water and fast meals to make, sleeping most of the day, until launch, then I live on about 2-3hours sleep for the first 2 weeks of the expansion.
I took launch day off so I can get to lvl 60 on the first day, and my fiancée knows and supports me to no-life most of that first week.
I’ve done everything in game I wanted in bfa so all prepared.
Thats the move right there
I’ve taken a week from my annual leave from work specifically to play WoW but if that’s not possible (it breaks) I’m sure I’ll find something to do. It’s been six months and I’ve not used any of my leave allowance anyway.
I usually sleep in quite a bit during the weekend so it shouldn’t be an issue.
How long will depend on how stable the servers are. I’m in no hurry to level so if I can’t do it for a few hours I’ll just do something else or go to bed.
I tend to have things I can snack on should I need to, and lots and lots of coffee. I’m astounded how much noise the Nespresso machine seems to make in the middle of the night when everyone else is asleep.
I have never managed to have a nap before hand but I will probably try to sleep in as late as possible that morning.
I have no set time that I will play. Usually until I feel too tired to carry on. In the past that has been around 6/7 am my time.
Update addons and tweak my UI.
Decide on the characters I want to play in Shadowlands.
Clean up my inventory; sell old reagents and unnecessary gear.
Prepare each character with gold, bags, gear, potions, and so forth.
Take a break from the game and the forums and everything else for a day or two.
Do some exercise.
Clean the house/apartment/room/mom’s basement/whatever.
Buy some healthy, nutritious food. Stock the fridge.
Get some good sleep.
Take a day or two off from work.
Stock up on your favorite snacks and drinks.
Take a long nap prior to the expansion release.
Get a refreshing shower.
Put on comfort clothes.
Play WoW.
Take intermittent breaks to stretch and move around.
Go to bed at normal hours and wake up at usual time.
Play more WoW.
Something like that. Business as usual. 
It’s funny but I have never stayed up for any launches except Diablo 2 and we all remember how that went 
I just go about my day as normal or I burn out. Also, I like sleep… not that it likes me 
this sounds perfect, mad props
You are not prepared!
WoW’s had its launch moments as well… 
Aaah WoD. And this is why I never bothered until a few days later.
Have fun, wait for the bugs to be fixed, play the game.
I try and stay as uninformed as possible, take joy in the discovery of new things, curse the heavens for things that displease me but generally just enjoy and explore at my own pace.
Endgame aint going nowhere and it’s not a race for me anymore anyway.
Oh and of course stack up on snacks.
My plan:
Reroll to AD server
Write RP bio
Install MyRP
