If you have good ideas for good respawn systems I could try take them into consideration and update my old C&H mission:
One of the best systems i've seen so far:
The one who are taken down isn't dead but just incapacitated for a few minutes.
Medic is capable to bring him to life in those few minutes.
Healing takes a lot of time so you need to secure location first.
Other players are able to drag incapacitated fellow man into secure location but not to heal him.
If the medical aind haven't come during those few minutes - man down.
