My Mechagnome was originally going to be an M&M Hunter, but Blizzard attached an unavoidable organic bird to them and sadly we are not allowed to shoot the bird and feed it to our party.
So I need a plan B.
What’s a good organic-free class for a cute robot gal?
I’m thinking of one of those electric warriors that they have these days.
BM hunter with robot pets.
The Hero Talent choices alone make that even worse than M&M.
I’ll either have to be stalked by Rexxar’s pets or practice necromancy.
I just want to be a cute robot gal doing cute robot gal things 
Alright. I’m outta here. I’m leaving the problem with YOU and YOU ONLY.
Great Johnny Rockets.
I have no idea what I did wrong this time 
Monk.
Some martial artists hit trees to build the resilience of their limbs. Mechagnomes cut out the middle man by skipping straight to metal ones. It’s only logical.
I think the best class for a mechagnome is a rogue so you can open lock boxes, and don’t have to worry about putting poisons on your weapons because they will not hurt you when they get on your clamps unlike other lesser races that have to clean their hands if they mess up with poisons.
My Mechagnome is a BM Hunter with Robot pets. The funky animals break the robot vibe a little… but the Mechagon Rifle matches the Heritage armor well.
I have a Mechagnome Rogue, but haven’t played him since BfA. My Vulpera Rogue is my favorite Rogue.
I think a Mechagnome Warrior would be cool, especially with some of the recent weapons from the Goblin Raid. Again, my Warrior is a Vulpera.
The only class that really motivates me to be Mechagnome over a Vulpera is a Hunter, because of its devices, and matching gun.
I liked the idea of a mechagnome warrior (especially since my warrior was already a gnome), but honestly the screaming sounds they make are pretty irritating. I know gnomes are supposed to be quirky but it is a bit over the top, I ended up just race changing back.
I have a mechagnome monk though and that is fun. Something very satisfying about punching and kicking with reinforced steel limbs lol
Get that Survival Hunter going, you got lamp oil, rope, and bombs, a nice solo pet that you built yourself, and some nice options for Transmogging that weapon this raid tier/season
Hunter with robopets.
I may be bias, tho’
come back in 2 years when we have the Artificer/Tinker for Last Titan
all the ducks will be in a row by then and Hunter will be able to fully embrace the Man & Beast fantasy and all the mechanical stuff can be reserved for the true machine class
DK
nothing says “Cute Robot Girl” like an undead while being not alive robot thing with rotten zombie pets.
Oh god the cuteness… 
Oh yes, this is actually also a good suggestion. I especially liked it back in DF s3 when it was more of a Bomberman playstyle.
Rogue with simple fist-claw weapon mogs = shredder.
warrrior, rogue, or hunter
Mechagnomes are most qualified to be Blingtron 7000s.
Mage was my first choice, and currently one of my favorites for Mechagnome. I am admittedly somewhat biased as Mage has been one of my favorite classes in general. There is also the access to robes, skirting around the whole thing they’ve got going below the waist if you don’t have the heritage armor yet.
Play as the Statue Class!
All you have to do is stand still, and let everything take a dump on you!
With or without peanuts?
