But aren't they both zones that cover 10 levels? If a level range is 15-25 then I expect to make 10 levels without having to repeat anything (i.e. events) or grind. I've been making 4 or 5 levels in each (what I'm calling) 10 level zone.
I think I'm missing a lot of events as I probably only do around 15-20 (unique) events in each zone (well up to the 15-25 zones, not really got past them yet).
My understanding is that every heart, POI, Vista and quick travel point is placed to lead you to another (set of) event(s). But I'm struggling to find one near every location.
I also really hate events, but realise I have to do them to have any hope of levelling in a zone. To be honest it's not even the events really, it the other players doing them.
Also, why are "Points of Interest" called that? What so interesting at every single POI in the game? To me they seem more like "Exploration Points" as I rarely find anything interesting at them.
I haven't seen anything anywhere to suggest you should level 10 levels in one zone, no matter what level range it shows, so not sure where you've got that one from. Same with the events, many events move over a vast area and certainly aren't limited to a single place. I'd be absolutely amazed if there were enough event sets to cover what you are suggesting. The Volcano on Maelstrom is a very good example of this as it covers about a third of the map and only has one event sequence. To me, Dynamic Events are there in addition to the hearts and can be a very quick, fun way of completing a heart, or in some cases several hearts.
As for the POI's, why shouldn't they be called what they are, can't see anything wrong with it at all, it's exactly what they are, points of interest, doesn't mean they have to be interesting to you.
