Felix, I felt there was more than enough dungeon with the enemy encampment in front of the Source Temple. Actually I didn't care to slog through that, and just used sneak to get past. I was pretty tired of the combat by then.
I may do that myself next time. I kinda enjoyed it the previous couple of times I've got to the end stages, but it's a fine line between it being fun and just being a bit of a chore. There's certainly enough combat in that section where the prospect of having to wade through it again feels like it's looming over me a bit.
