I've finished the main quest before, and I have a character who is presently engaged in it.
I have a great deal of curiosity, and I enjoy the game world tremendously. I can’t imagine skipping part of it on purpose. Locations, NPCs, dialog, notes, I want to see them all. No matter how many characters it ends up taking to get me into everything.
Most of my characters do not get drawn into Jauffre's net. But I still very much enjoy doing the main quest (at least as much of it as they survive) with the ones who do.
