Warrior is fun since… well it just is as a Gnome. That and you can have some good transmog as well. Using the right parts you can even look like a Tech Warrior using the one staff from the Siege of Orgrimmar Raid.
Also Rogue wise you are small so harder to detect as well, well more so than bigger races anyways.
It’s the Napoleon Complex. You see this in other places, when the 5’2" guy that looks like he spends all day at the gym jumps out of his giant truck with lift kit. Overcompensation.
They have disgusting baby bodies and old people faces.
They are crimes against nature, god, and sanity and should be exterminated.

Braised Gnome

This is gnomish discrimination.
As a Goblin I approve.
You underestimate the gnomes!
As to which race, afraid that’s classified Asahina. 
I’m thinking rogue. Might be fun to be sneaking around everywhere.
It’s traditional. And jealousy. But mostly just habit.
I love my Gnomes, even the weird ones with mechanical bits.
Brother?

Oh, dear, god.
I have a twin.
Omg my thread has produced a gnome family reunion!
It is just me in a different universe. Just always wanted to make the joke.
They blink one eye at a time. It’s not natural. That’s not a joke from me either. I can’t stare at a Gnome’s face too long cause it creeps me out on that one factor.
Lol, do they really? Now I need to go make one and look.
What if all gnomes were named Mineta
That’s some next level hatred there.
I have a warrior for the express purpose of looking like a canon ball when I rush the enemy lol
Just picturing that makes me smile. 
Someone once mentioned a mount being made where you can launch a player at your enemies for the sole purpose of blowing up like a kamikaze attack.
As a Crazy Gnome Warrior I was all for that idea.
Even thought of adding a macro that lets me “/yell” “HEEEEEYYY YOOOOOUUU GUUUUUUUYSSS!!!” as I am being launched.
Yeah, it’s the little things, isn’t it?
