So the three pillars of play are combat, role-playing, and exploration. Combat we discuss a lot and have many rules to make dynamic and exciting, hordes of monsters, reams of magical spells, and numerous tomes of battle equipment. Role-playing is theatric, and we have seen it done with character arcs, accents, and know how it has been long elevated as the height of good Game-Mastering ("Role-play" NOT "ROLL-play.")
But exploration? It's the neglected middle child of the pillars. Why? I think because it's the in-between of interesting things.
It's the trek through the wilderness listening to the DM trying to use purple prose to describe the forest that exists to waste your time between getting the quest from the haughty noble (role-playing) to the bandit hideout (combat). It's the long, featureless corridors that may contain a ho-hum trap (which is likely going to be less dangerous than a single monster of your party's level), but that trap will be avoided with a Passive Perception check you don't even have to roll. That hallway may connect two exciting combat encounters, but the hallway itself is just a line on a flowchart.
Exploration is the session that you're buying supplies for your journey and making preparations, which can be easily avoided with a die roll. ("Did we bring enough food? Here, let me roll randomly. Good, you have enough food.")
How much game time is wasted on exploration? Would the experience be better by simply asking the players: "Do you want to go to Fight A with the troll barbarian or Fight B in the vampire's crypt?" We could speed through literal sessions of actual games that require wilderness travel from the starting town to the dungeon.
But the only advice I've ever seen for improving exploration mode is to use better descriptive phrases, wandering monsters, or have a few skill checks that are going to ultimately have no impact on the game (maybe you lose some hit dice, maybe have to spend a few spell slots, etc.). But even with most of that advice, it's telling you to make exploration mode better by adding combat (wandering monsters).
So what do you think? Am I wrong on this?
