But that's the point - you work harder = you get more benefits. And isn't it actually better that you CAN actually do a speed run if you'd like (even though the best you'd build would be a Meh-quisition and not many people will be your friends) or have a choice to do more stuff and chisel our Inquisition into exactly what we want it to be?
Call me crazy, but personally I enjoy being given that kind of choice.
But, WHY would we want to do those quests?
I mean, I know why I would rather help Redcliff than abandon them. We meet fun characters, we hear the desperation of the people of Redcliff, we can help them prepare, we can fight in the battle and see it all pay off when they all survive.
In the Exalted Plains, for instance, you kill a few undead and Abominations and suddenly soldiers teleport. I can't speak with any but three or so and all they have to say is "We were overrun, maybe those over there were overrun too, you should check it." and you repeteadly do this until you encounter the man behind it who is just another mook who is "connected" to the main plot because he serves Corypheus.
So, sure, these quests are, theoretically, important. And they play a role in defeating our enemy and increasing the influence of the Inquisition.
But they are BORING. There is no real reason we should feel motivated to do them beyond being a completionist or needing a few points more.
It would be fine if it was one or two but virtually every side quest outside of the main areas is like this.
