Don't get me started about realism in games. Because we both know no game is even remotely realistic.
Not being able to magically heal definitely helps. Not being able to get shot 6 times and continue running off in a full sprite would help the realism. Grated ofc theres a lot all games can improve on, but bullet damage is a no-brainer imo. The amount of bullets it takes to kill a person, especially character models not wearing any type of body armor is ridiculous.
