Sure but dont you figure it actually didn't require as much skill or art because EL delivered..Any chance your formative play experience with 4e included Keep on the Shadowfell, Thunderspire Labyrinth, and/or Pyramid of Shadows?
(Because, while the middle one was actually mostly pretty good, each included at least one example of completely whacked encounter design.)
...or, y'know, alternately, maybe your DM just liked killing you...
Vs encounters run closely to guidelines, 4e characters were often dropped, sometimes very greatful for the next long rest, but rarely killed outright, let alone TPKd. You could make that happen pretty easily by just dialing it up - EL mostly delivered as advertised - but you could, with enough experience & artistry, make any ed as deadly or survivable as desired.
