I really very much like the 4E death and dying rule.
This can still be done, I did it recently when I used the ritual Shadow Bridge to bypass parth of the encounters in a castle. I this case lucky for us as we were on a clock and doing all the castle encounters could have slowed us enough to prevent us from completing the mission on time.snip
Several years ago I ran a 10th level 3.5 game with friends. We're pretty casual, and didn't get to game often. I had plenty of time in between sessions to prep, but often, I'd forget about exactly what the PCs were capable of. I planned an absolutely epic battle in a graveyard that would've lasted most of a night, been pretty cinematic, and a lot of fun. Basically, players had to jump from crypt to crypt to avoid hordes of low level zombies (they'd be minions in 4e), and then deal with some bigger, nastier baddies at the top of this graveyard cut into a terraced hillside.....
And that's when the priest says "oh, I'll cast moon bridge and then we'll walk from here to this high point over here" effectively bypassing the *entire. encounter.*
I'm much more aware of stuff the players can do now with the 4e power system.
