Tales of the Blue Dolphin

I have to say, I really liked it when they did away with anything that was "per-encounter", and I'm sad it's back. I find it too fourth-wall-breaking, making it hard to mentally stay in the world and in the character, not to mention that in many cases, it's hard to adjudicate when one encounter ends and another begins, or what qualifies as an encounter. If you're fleeing from monster A and run into monster B, is it a new encounter? Does it depend on whether monster A has lost track of you? What about traps or puzzles? If you're walking through desolate woods and come upon an ornate marble fountain bubbling with crystal clear water, obviously some sort of puzzle, is that an encounter? In 2E or whenever, it was an encounter. But suddenly being able to use an ability again in such a situation is absurd. (DM:"You come upon a fount--" Player:"I use Healing Surge!!")
