I've clocked about 100 hours and finished a few days ago:
Pros:Superb cast of characters, easily the best in the series in my opinion. It is mainly what drove me to finish the game.
Great cinematic feel to some of the cutscenes
Some beautiful scenery and general architecture.
Pretty interesting lore, really expanded upon the first two games.
Pretty epic dragon fights, better then Skyrim's anyway.
Awesome soundtrack, one of the best in recent memory.
Cons: Dull combat system overall. The dull part started to really hit me at about lvl 14-15. I played on Normal though, so that's probably part of the reason.
Excessive amount of shallow side quests which fell like padding and not tied to the main quest enough. This is the main reason I've lost interest in playing my second character.
Main plot was too short and lost momentum after the 1st Act, although there are a few highlights beyond that.
Cliche-as-hell villain, basically what you'd expect.
Epic loot becomes really underwhelming, particularly if you craft most of your gear. I like the fact the crafted stuff is better then what you find, but there needs to be exceptions.
Shards....ugh. That's all I'll say. I didn't think they were worth it.
Conclusion: From what you've written you'll probably enjoy Inquisition overall, everyone and their pet monkey can pretty much agree it is way better then DA2 at least, just don't be afraid to skip some quests because there's too many frivolous ones.
