If I'm losing PCs at that rate, at some point I'm just going to stop trying. I'll just roll up barely disguised carbon copies of the lost PCs and continue apace. I'm certainly not going to actually try to craft a three-dimensional character.
If you're losing PCs at that rate, you're probably not trying very hard to stay alive in the first place. Smarter play tends to result in greater odds of survival. As well, sometimes throwing your character to his or her death is what makes for the best story in a given moment. I've done that myself a few times.
Bear in mind, too, that my pool of players is quite large, so it's not like I have had 4 players lose 20 characters in the last year.
