One of the main reason of no one uses heal quick scrap in fractal/raid/strike is lack of boon, especially might, fury, and stability.
Blast gyro might duration is less than its cd time even with quick+alac+100% boon duration, which means might generation is not consistence.
Currently, the only option for heal scrap to bring fury is to bring rifle turret, which means either quickness drop (replace gyro) or might/healing drop (replace e-gun).
Hoping heal scrap can receive some love.
