Which combo makes you think “yeah this guy probably has his life in order”
I’d say any shaman. But mostly dwarf restos.
Edit: no no no. I mean the player. Which race/class combos indicate there is likely a total chad on the other side of the keyboard
There are a lot of meanings to that phrase.
When it comes to having all the smarts but not a lick of sense as to how to use them, gnome mage, with all gnomes getting an honorable mention. Goblins kind of fit in this category, too.
When it comes to having the wisdom to say “screw this, let’s go have a beer,” I’d say the monk and shaman communities have this pretty well figured out.
Definitely Night Elf paladins…oh wait…
Zandalari Paladin I’d say
draenei anything or vrykuls.
Male Human Paladin.
Night elf priestess. We are the leaders of our respective civilization. It doesn’t get much more in order than that.
Do you mean like, In character or out of character?
In character, Gnome mage. However Any gnome caster would do.
Out of character? None of them, every race and class has their dumb dumbs.
Tauren Monk
Back in TBC all the shaman I knew where cell phone sells.
That’s a small sample size but seriously it seemed like everyone I met was a cell phone sales person.
In lore? Potentially the highborne mages. 
Panda Monk
Was a common job back then. I dated a guy in college who did it. He worked part time at one of those kiosks in the mall. You know the ones. Remember malls? Ahh…
Night Elf Death Knight.
Who needs order?
I prefer the flames of hell myself 
It’s not too late for you to come back to the light of the Moon.
Probably human unholy death knight, or undead disc priest. Idk why even.
Now that you mention it I think maybe they suit you! I thought Death Knights liked cold and ice and snow and mountains though. Like Norwegian black metal in an RPG class form.
It wasn’t a bad gig. Friend of mine made more money with commission than I did. To be fair I am a social worker and we don’t make much. (Note I only have a BS, the MSSW’s can make good money but not as much as other MS programs)
