Well, like I said, there are still tons of rifts along the countryside, and no regular small surprise force is going to be able to do anything about that. Hell, the game even flat out shows you that there are scouts assessing the situation in each area right before you arrive for the first time, meaning that steps have already been taken to minimize risk to the Inquisitor as much as possible. The Inquisitor is only brought in when the situation is severe enough to be brought to your attention and there's no other options.
Inquisiton had a lot of problems, but how it handled the main character was really not among them. Sure, you can go on solo adventures with the Inquisitor, but I chalk that up to gameplay oddity instead of an actual narrative fault, since you can do something equally dumb from a narrative standpoint in most other party-based games too.
