How can a Mechromancer be optimized for Ultimate Vault Hunter Mode

Salpe86's Assassin's Guide has been a great help in gearing my character up to better handle Ultimate Vault Hunter Mode. Since following his recommendations, I've gone from constantly fighting for my life and burning through handfuls of ammo clips when facing what should be the most trivial of enemies to killing even Badass-level monsters without having to reload more than once.

However, my wife hasn't been so lucky. She plays a Mechromancer and still has trouble even down to True Vault Hunter Mode. She only made it into UVHM with the help of my escorting her through the endgame missions of TVHM.

I presume the weapon selections recommended for Assassin will probably port over to Mechromancer fairly well, but are there any changes I should make to that - does the Mechromancer tend to handle some particular weapon types better or worse than Assassin? How about Shields, Artificats, and Class Mods? What skills are essential for a Mechromancer in UVHM?

wow, old question, so my answer is probably late.

I play a mechromancer. I've not gotten to UHVM yet, but I've solo'd most of TVHM so far with very little problem (I do die occasionally, but I never got 'stuck')

I invest in anarchy (I keep the stack limit at 150) with maxed type I iconocast and rational anarchist. I always pack a one-shot jakobs; even if its weak; purely to build anarchy; though you have to be far from the enemy and stay safe while you charge it up. It takes very little time to get to 100 stacks and Deathtrap does a fine job at keeping them from getting to me while I charge up. At about 100 stacks or so, I switch to my main guns and start chewing through enemies very quickly. Anarchy, at least for me, has been key for Mechromancer. Shotguns are your friend; 5/5 close enough, standing close to the enemy, and 150 stacks of anarchy = awesome offensive power. Throw in 5/5 bloadsoaked shields and you can stay alive as long as you keep killing stuff; an easy thing to do with the anarchy/weapons mentioned above.

Rest of my points generally go into Best Friends Forever tree to beef up Deathtrap. He is seriously a beast even on TVHM late game; so long as you spec him for it.

I do admit; I am nervous to see how this build fares in UVHM..
