It's moved over the years from the meat grinders of the early editions to the much more character focused ones now, but some things haven't really kept up.
The big one being character death becoming trivial midway through, and the combat kinda being centered around that. Death doesn't mean much when you just keep reviving them, and it's left up to the DM to figure out how to balance that (since the 5e economy is a mess).
5e long ago should've adopted a downed/injured system like much of the competition, with death being much more rare. Then again there's about 100 other things they should've done, and it's pretty clear they won't, so meh. Guess it just sits on the DM's
