I guess a ranger's not much good if they aren't agile enough to keep out of the way! I forget exactly what build I'd ended up with now, probably some sort of badly-planned mix-and-match in my case. I know I did often swap between a sword and a bow.
In my case there's a fine line between a challenge and a chore, and given that I generally play for the story and adventure rather than combat prowess, I have no qualms about using god-mode (I think the Developer's Cut has one...) to get through awkward gnarly bits.
