I had a couple scouts die to bandits, and got a little tired of it, so I married up a scout with one of my champions to protect him.  As soon as I did, the view distance of the party changed to the champions smaller view distance.  So I had to disconnect the two, and my scout ended up dying again in a few turns.

This makes no sense, as the scout won't suddenly have worse vision traveling with someone who can't see as far.  It should be the highest view distance of the group gets used, not the lowest.  This isn't a case where the group is only as strong as the weakest link, in this case it should be the strongest.
