Solo necro is still BS

Just 1v1ed a Solo player after my duo partner dying to a squad that i fought off and killed. Solo shows up to 3rd party. I finally was able to kill him, and before i even have time to bandage bro is back alive at full hp. Honestly just kinda dumbfounded as to why that is a thing. Why is there 0 cooldown for self resurrection, giving them a distinct advantage. Having 100% health too is ridiculous imo. Am i trippin?
