When I see mechagnomes I feel like telling them this: "Homer, you're as dumb as a mule and twice as ugly."
They should have been a quest unlockable extra barber customization like night warrior for gnomes. Right now they stand as the least played race and can't help feeling like that allied race slot could have been taken by literally anything more interesting.
What would you have liked to get instead of diaper bots?
Broken or vrykul come to my mind first.
