Yeah the diaper thing was hard to deal with. I faction changed my Mechagnome as soon as I got the heritage armor.
However, I gave them another chance and race changed my Mage. Wearing a robe helps A LOT.
p.s. When I did, I discovered the name Angleyne was available (Bender’s girlfriend; Flexo’s ex-wife.)
First things first.
OP has one post. At least have the balls to post on your main.
Second, while I’m happy to request and accept new options for Mechagnomes they are likely (blizzard) limited by the way models are designed for WoW.
So we likely wont see one arm mecha and one not.
Further if you want to get rid of the “diaper” look which… I question anyone who actually thinks thats what is going on, you can just wear a tabard one of the larger belts or a robe.
Honestly ya’ll just weird I think…
This would be welcome as well as releasing our other two Heritage armor colors.
And even those have been… improved.
I still wish we had options for where we placed our mech parts.
Imagine a mech torso.
I just lurk mainly on the forums. But okay.
Sure you do. 
I mean this is my main so ya
You have my deepest sympathies, my faux fashion flamingo. You have revealed your true inner beauty for all too see before you, and it is an ugly sight indeed.
Fret not my marvellous mechanical minions, for you are all welcome within the firm embrace of my tender tentacles.

My optical sensors indicate you need to step up your mog game.
Mog game can only go so far without leg and boot mog
like this:
I can deal without boots. I haven’t had boots in 16 years.
But working without gloves and sleeves is interesting.
One set does not constitute a good mog.
They need more options!
Because the game has actual creatures called abominations, I still can’t put them in the same category. 
Let me know when we get the customization option for exposed guts with a combination of living Gnome guts and wires, then I’m all for it!
(Sorry, just kind of being a brat about definitions. I’m tired today.)
Truly I enjoy every post of yours I see.
Then like this:
Mogging a Mechagnome is pretty simple. Pick your arms and legs, and then you mog AROUND them.
Consider your arms and legs to be part of your transmog, and their starting point. Like a built-in Racial Transmog.
Or just take everything off and wear your tabard, that works too.
No it is very limited.
Even you have to admit it.
More options and the ability to choose where your mech parts are located would go a long way in customization.
Mechagnomes are awesome!
Most folk aren’t creative.
I think what makes mechagnomes cool is that you can go full robot.
I think what makes mechagnomes not cool is that these could have been cosmetic options instead and alliance could have got sethrak .
It’s an update, we cant punt them now without hurting our feet. nerf please
