What's the alternative? Stuff like potions and health packs aren't exactly realistic either.
To me, it isn't whether it is realistic or not, since most FPS's are nowhere
near realistic.
However, I feel as if regenerating health takes out a large chunk of strategy and common sense to a game.
If you are low on health, you snoop around trying to get some more health without being noticed by the enemy to stay alive, that's a lot of fun and a challenge.
A sniper can than become more effective with non-regenerating health(These examples are not including head shots).
A sniper can support their other teammates by weakening the health of enemies before another teammate gets to him, making an easier kill.
A sniper can also pick off enemies easily that have been injured.
Without regenerating health, you can't just charge in guns blazing and hope you succeed. You need to have more strategy than that.
