This bugged me with Fallout 3 and New Vegas, very jarring hearing the same voices again and again. I've been playing LA Noire and looking through the manual it has 4 pages of voice actors. Now I know Bethesda probably don't have Rockstar's budget, but it makes a huge difference to the immersion not hearing the same voice for different NPCs.
As for your main point, I agree, I've never understood why characters are rarely used for more than one mission in RPGs.
