Nope, that won’t do. I want my muscular male body, otherwise it is not fair.
I would go to Pig and whistle, order a beer or two and think what the heck is going on and what to do next. Probably I would try to find Khadgar, perhaps he can help me somehow
Humans gain nothing? I should gain atleast 50 kgs in muscle judging by how my warrior looks!
race up to jaina and murder her as painfully as possible. Then, if shout “youre welcome” and all races colours and creeds would race up to me and garland me in every fruit and flower they could find, as the horror was finally over … finally, we could rejoice and live out our dreams in joyous glee. The world was freeeeee, freeee of the nightmare that is jaina, the horrible storylines, the terrible voice acting, the godawful dialogue that makes no sense, the terrible haircut that looks like someone stuck a st Bernard behind each ear … we could finally all live in peace and harmony… rejoice rejoice, that pointless inconsequential witch was dead. REJOICE
that’s what id do
I’d savour the moment, It’s not everyday you become a Glorious Gnome.
I head straight to goldshire
I would look for Gm Island and a hearthstone. 
That’s cheating!!! 
I would start to work on Teldrassil with some sort of fire proof finishing agent.
Get killed by paladins during events that occured in plaguelands because Arthas is a bully!
I don’t really have a main, but one of the chars I play the most at the moment is a male night elf…
I think I would find a mirror or some still water so I can look at myself 
Nelves have abs and are tall, the opposite of me 
I guess I could spend some time looking at myself before I start to cry because I can figure out where I should go 
Deathknight’s certainly are a unique case for this one, same goes for demon hunters.
But I think we can exclude classes so you’d probably be a regular orc with arthas having no interest in killing you 
unless you manage to get yourself ghouled sometime later that is.
Well lets pretend Arthas does not pull the stunt and send us to die, then I would probably join the rfest of the death knights murdering and killing…
… oh … darn… but i would most certainly look good as night elf, and nothing regular on me !
But would you be doing it unwillingly or … 
?
Well if I answer this truthfully alphabet agencies would contact Blizzard for my address. 
But 
if I was on my goblin, I would spend a lot of time flapping those adorable huge ears 
And then I would find a shop, maybe that racial for best deal works 
not meaning to sound blue but i would just throw myself off bridge or jump into sea if the imbalance would still be in the world i awoke in… would not wish to be a part.
I would have said i would go to darnassus and just live with elves but no even that gone now so i would not bother…
First thing I’d probably be saying… now what I’d do… uh… I dunno probably explore.
Stare at my boobs and wish mine irl were more like my chars.
Most likely tell someone what’s going to happen, wait for everyone to realise I was right and become a giga fake far-seer and become respected while never leaving the safety of the drag
I’d die, because of;
