as much as i find this game awesome and amazing
I find myself right after skyhold (been playing 10-15 hours post skyhold) I havent been doing any main storylines/major side quests after this, just running around doing side quest, companion minor quests and talking to residence in skyhold.
I'm at the point now where i want to level up a bit more before i continue the main story, but after an hour or 2 of gaming i get "bored" of running around aimlessly. I kick off the boredom easily by doing other task and being distracted, but there are times where I feel like the enemies are too tough so i got exploring somehwere else.
Example, i wanted to clear hinterlands before i did any other major exploring of other areas, but there are mobs that are high level.
That's intentional. You're actually meant to leave the Hinterlands and go and explore another area, which have their own series of significant quests. At your level, you should check out the Storm Coast and Fallow Mire, at least. Don't try to clear the maps completely, that way lies madness (heck, in some maps areas are even gated by war table missions to prevent that).
And that's the thing, going back to the OP: outside the story quests there are still a ton of significant quests in each of the areas, with an ongoing storyline pertaining to the area. They're just handled through non-cinematic conversations and the environment. The Hinterlands are a good example of how your actions will change the land.
Even the most obvious collection quest (the shards) have an actual purpose in the game, unlocking some pretty cool stuff. As for the requisition quests, I'm not sure what the complaint is all about. This is obviously meant to be a crafting alternative to gaining power, and obviously quite optional. I stopped doing those long ago (I'd rather keep the mats for actual crafting, and power points aren't in short supply).
