I hit a wall last December where I couldn't stand the mere idea of firing up the game so I moved to other games until I returned to Inquisition maybe a month ago. Since then I've completed another, very satisfying run which is now my canon. In every playthrough I always try to find the perfect pacing and I think I'm pretty close to a good balance now.
First of all I use this mod: http://www.nexusmods...tion/mods/479/? - which eliminates all waiting for the war table missions.
I usually complete all the Hinterlands, the Fallow Mire and the Storm Coast *before* I do 'In Hushed Whispers' (when I began it yesterday I had 85 power points). This goes pretty fast if you use the following mods:
Ardant Blossom Store http://www.nexusmods.com/dragonageinquisition/mods/814/?
Complete Schematics & Collectibles http://www.nexusmods.com/dragonageinquisition/mods/866/?
So you start with tier4 schematics & mats. Note that I don't bother with any of the shards, or the astrariums, or the mosaic pieces.
Then I go straight to In 'Your Heart Shall Burn' and onward to Skyhold. It's at that point that I usually restart with a new character.
However if I decide to continue this is where the pacing derails. BW made the questionable decision to put 'Wicked Hearts and Wicked Eyes' and 'Here lies the Abyss' on an equal footing when the former should have preceded the later...
Be that as it may I enjoy the world, I enjoy moving in it, I enjoy the story and most of the characters (even Sera is growing on me if you can imagine!) so I see no reason to no replay it. And when I get bored there are always other games to turn to.
