In my Unit Spotlights, my grading system considers how well the unit performs, how useful the unit is, and how it compares to meta units. Where and how to obtain the unit or how rare the unit is falls in a different category that does not fit into my grading system.

Certain units, especially Honor Summon units, would gain an unfair advantage simply because they are easy to obtain. Most Unit Analyses wouldn't use rarity or availability as a factor of their grading systems anyway.

Hope this clarifies things. :)
