Great proyect.
I understand that create a medical system its very complicated.Its depends that players that you want in game .If create that respaw medical that all 99 % games actually have you win more players that game but.... for now all i see in the video preview and like a lot. Its time to create a medical system with damage parts of body (head,legs,arms,ect) a mini system easy and fast to medic team member try to revive/helps the team member with injurys.... of course with a limit life ( two or three serveral wounds and two or three basic wounds) after that the medic cant help the member team and the player its out from the game (death) . With this medical sytem the player thinks twice to cross a corner street and think that cover its important if he wants play all the match.
Hope thats help .
