That sounds about right. It was back in the day when TKs had to have two characters - I believe them and Brets were the only armies to do so, and now its just the Bretonnians.
Its impossible to make a legal 500 points list without the Lord with the Virtue of Empathy.
Two naked paladins (of which one is the BSB) cost more then 125 points allowed. Even if you give one the Virtue of Empathy.
Bretonnians ARE NOT a pure Knightly army.
Half the army choices consist out of Peasants and Damsels.
'Pride cometh before a choppa in the face'
In my gaming group we have a house rule that the bretonnian BSB doesn't count within the maximum hero points at any point cost.
As it should have been when they updated the rules to 8th.
But yeah, using a bretonnian lord with virtue of empathy fits with a legal army.
