You know what would be a game changing, and interesting, trait change for Scrapper? Decisive Renown, and Rapid Regeneration. Switch places with both of those. Could make for some interesting builds. One could opt for more support via choosing Decisive Renown over Mass Momentum or Expert Examination, whereas one could choose to be more offensive running Mass Momentum rather than Decisive Renown and Expert Examination, etc etc. Also, it could really open the way for true 1v1 bruiser builds, as you can opt to take Mass Momentum for more power while also still having the healing benefits gaining swiftness and superspeed from other utility skills (Elixir B, Slick Shoes, etc). Maybe this could be looked at and implemented in the coming patch? What do you other Engineers think?
The greatest enemy to improvement, is ignorance. But the desire to learn will cast ignorance into the fire.
