How about having to collect the dog tags of dead teammates in order for them to be eligible for respawn.
Much like collecting the banners on Apex Legends.
Even potentially a time limit in order to retrieve the dog tags.
As an example of the current mechanics failing, I played a match yesterday where I stalked a very organised team and wore them down over time, using both my heal kits to do so. My 3rd attack i downed 3 FT and in the confusion lost track of the 4th. I then went and got the 3 trophies feeling quite accomplished.
However, the 4th guy had ran off and started the reinforcements and within a few seconds I was back to square one with no med kits left and a smidge of health remaining. I lost obviously.
This mechanic doesn’t work. However, if he had to collect the dog tags in order to revive, that would most definitely made it a more interesting game.
