I'd say that the reason is closer to "dying and creating a new character every session cuts down on the roleplay and makes fighting the only thing worth concentrating on." Why bother with real roleplaying if the personality you so painstakingly created, and the in-character friendships and contacts you've worked so hard to form, could be taken away at any second? Also, death is no longer a certainty in 4.0, as fate plays a part in whether a resurrection even works. This means that death has more impact and balance; it's more nebulous. There's no longer a sort of "resurrection hump" to cross, before which you're basically screwed and after which death is a mere annoyance. You should give 4.0 a fair chance; despite being flawed, it circumvents a lot of things in 3.5 that were plain nonsense. —Wynne
That just plays right into the "dumbing it down" argument. If you're smart about how you build and play your characters, you won't die very often in anything outside of the Tomb Of Horrors. On the other hand, you would have to be downright retarded to lose a character in 4th ed. Now a valid argument would be that 4th ed lets you get back in the fight faster. If that's what you want, 4th ed really is the better game. — gibberingtroper
This goes here, as it's an argument not examples.
