something liked this was in arma 2 dayz server i played on before exile. had it set up so if you died within 250m of your bed, spawn point, you could not use it, so if your base was being attacked you wasnt respawning there constantly. and also had it to use once per restart. personally not a fan of it but if majority of people wanted it, there are some ways like i have said to make it less OP.
