Tbh it was a joke post,

I do miss the old version of upgrade, but I miss it in a sense that I saw it as a mechanation racial trait, and not an engineer skill.

I used it as a way for mech basic attack builds to incorporate a rogue promo in with a lot of race based synergy, end result was pretty much no engineer shenanigans and just super buffing yourself.
