"overall it really boils down to mitigating yourself the most from bad RNG as you develop your unit roster."

That point is basically the main solution to getting the stuff you want from RNG gacha. Even with RNG, there's strategic planning involved that can make getting your target unit easier. At the same time, RNG will never go away, and you can only inhibit it as much as you can before it decides to reward your desires or spin you for another round :3
