Heres some information regarding the boff traits by quality. So you can figure out the quality of the boffs in your roster.
Common BOffs will have 2x Standard Traits and 2x Basic Traits
Uncommon BOffs will have 3x Standard Traits and 1x Basic Trait.
Rare BOffs will have 2x Standard Traits, 1x Basic Trait and 1x Superior Trait.
Very Rare BOffs will have 2x Standard Traits and 2x Superior Traits.
I would add to the boffs biography, what quality they are for ease of reference in future. You could also add to the name at the end -P or -VR etc... To denote the boffs quality. So you can quickly scan your roster, to see what the quality of your boffs are. Hope this helps.
