I don't understand the frenzy with RPGs having a vast majority of their content being side-quests. As far as I remember it has always been this way.
Hell, I still remember finishing absolute classic Fallout 2 in like 5 hours, with no sequence breaking even. I just did nothing but imporant quests, and if I waned to sequence break I could have finished it in 2 or 3 max. Get to San Francisco as a dumb character, speak to the Brotherhood guy, get to the oil rig, use mentats to pass speech checks, finish the Rig, persuade the squad to help, kill Horrigan, roll credits. Does it mean Fallout 2 has only 5 hours of ''real'' content?
Baldur's Gate 2 was also almost exclusively optional content. Things you had to do; Irenicus's dungeon, 2-3 side-quests for the thieves/vampires, Spellhold, a fraction of the Underdark, assaulting Bhodi's lair, elven city, kill Irenicus, roll credits. Does this mean that BG2 has only this as ''real'' content?
Dragon Age: Origins? People beat the game in under an hour by bypassing the treaty quests with a bug. If you power through only the main quests I'm positive you can finish it in less than 10 hours. Do the Origin, go straight for the treaties in the Wilds, do no side-rooms in Ishar, walk past Lothering, make a beeline for Irving/Witherfang/Connor etc.
Now, could Inquisition have cut down on the number of busywork content and delivered more quality side-quests like Still Waters or the haunted mansion in Emerald Graves? Yes, definitely, it would have improved the game. But it seems to me RPG players complaining about a game having the majority of its content in side-quests sounds like a FPS player complaining that there are too many guns in the game.
Besides, I'd take one well-done Inquisition-style main missions, with their custom locals, big amounts of banter and choices, rather than a hundred DAII-like ''main missions'' which were the same as any other ''go kill this guy'' quests in the same copy-pasted areas as everything else.
