Yeah AEDs can be used by literally any human with a half functional brain due to the idiot-proof design, but in CM defibrillators are literally necromantic magic tomes which raise the dead. They’re not even in cardiac arrest, they’re just dead.
It’d be a really bad idea design wise to increase the number of people able to revive other players- Attriting medical capabilities by overwhelming medics (or killing them) is a core part of the gameplay balance. Survivors should suffer from medical attrition significantly since there’s only a handful.
