On RW/Engi non-shield thp generation after last patch

I’m playing mostly Huntsman these days and have not touched lil gobbo for a while.
Imagine my disapointment when i found out that twin hammers/stagger thp gen combo is not that effective as it was before.
So, fellow Bardin enjoyers!
What instruments you are using for grinding thp these days Apart from his two shields?

Thanks in advance.

Unchained bot, Merc bot and when playing without a shield do not do crazy stupid things that leads to being hit. :smiley:
