The change Second Wind actually needed
Second Wind needs to be like Aftercare, where you simply need to finish a teammate heal to activate the perk.
The 1 full health state requirement is what makes the perk unusable. There are so many scenarios where you only get a partial heal and have the perk sitting in limbo, which is just frustrating and makes it much more difficult to use then you would expect.

Exactly. If another survivor heals themselves for only 1 seconds and you heal them for the remaining 15 seconds it won't work because it needs 100% heal progress right now. Hopefully they will change it.
