Unfortunately i think that even with this errata Salvage won’t be a strong card because of the 0 strength and also thereby it’s susceptibility to Parasite. In my Hack i was generally avoiding increasing the power level of cards. I would consider perhaps combining both the Salvage errata i suggested and the removal of the “can be advanced only while rezzed” clause that @Industrial_Memetics suggested.
Incidentally, i think it was generally a mistake in the game design not to make Tracer ice without the other main three subtypes ( Barrier, Code Gate, and Sentry ), given their inbuilt alternative to breaking. I would have liked Runners to need to use a variety of AI solutions and or link in a deck. ( Note that most posters here have disagreed with that. )
