Haening

I have pointed that optimally you might need a med-kit and Adrenaline in order to make it work completely.

Nop, Ace is the quietest. Also, Unbreakable is too situational, Sprint Burst is better than Dead Hard, and Borrowed Time is low-key situational. Partially because if every survivors run Sprint Burst, it's pretty much a guaranteed escape most of the times, thus making it worthless.

Possibly, as a situational perk, I would consider Adrenaline to be at the top. Especially in combination with our build. So, you will have to bring a med-kit, and use Adrenaline instead of Self-Care. Repetitive pattern, keep doing 99% heals, do generators, once your med-kit is fully used your team and you probably did 4…

The point of running self-care is to get stuck at 99% heal and then simply tap it whenever you are getting hit. But until then you need to abuse the Resilience benefits combined with Spine Chill to gain as much time/distance. This could also work with a med-kit, I reckon. But I'm not seeing what else you could put instead…
