I read "just have more encounters per day" over and over again.
Never do I see any of acknowledge:
1) the game rules do not force the 6-8 encounter day in any way form or shape. There's nothing even close to formal aids to help the DM out. She is completely on her own in creating story based timers.
2) this is utterly incompatible with wilderness exploration adventures ("hexcrawls") or long distance travel adventures
Not really. I've mentioned this in another thread, but, actually, this is pretty easy to do - you simply make random encounters into random events. Instead of having one, and only one, group met during a day, a random event includes two-four encounters, spaced some time (but less than a short rest) apart. So, the bear wanders into your camp, the sound of fighting attracts that troll and the party of orcs that was hunting the troll stumbles in some time later.
Ok, that was a pretty quick and dirty event, but, I think you get the point. Making one big encounter is far less interesting than slowly building tension by stringing together three encounters.
3) no official adventure follows this guideline AT ALL
Really? We're playing Hoard of the Dragon Queen right now. Just finished up the section where you go to the castle in the swamp, with all the lizard folk and whatnot (sorry, terrible at remembering proper nouns) and we were pretty much (mostly through our own actions) forced to deal with the entire castle in a series of encounters over a single day. Now, I don't know how much of that was the DM ad-libbing and how much was in the module (his comment was that there was very little guidance actually given), but, my experience (very limited so far) with Hoard is that strung together encounters are pretty much the norm. Same went for the Phandelver module as well. Again, this might be 100% due to the DM, but, it's certainly not impossible to do in the modules.
Is a long string of individually trivial encounters (where the only challenge is to conserve resources) any fun?
Sorry, but the level of advice which basically says "do 6-8 encounters and all problems go away" is incredibly and frustratingly short on discussing the overall picture.
IMO? Yes, absolutely. It is very fun. Far more fun that single, slogging encounters where everyone blows all their big guns in the first two rounds and the rest of the fight is mop-up. For me, the fun encounter is the one after that one, when the party is down on resources and NOW has to deal with a challenge.
Note, even just stringing three encounters is generally enough. You don't have to do the 6-8 every day. But, you generally do have to chain some encounters together and not allow for short rests between every encounter. Forcing players to actually conserve powers makes the game far more interesting.
If the PCs are in the habit of popping downed PCs up again in the middle of combat with healing, can
they really object when the monsters notice this & start finishing off the fallen?
Fair enough. Again, I haven't seen a lot of the "whackamole" behaviour, so, it hasn't been an issue for us.
