Strategic Operations : Equipment Rating and Quality Rating, pg. 167, 168 tables.
I believe that the A - F designations that is reversed from earlier incarnations of these systems (Field Manual Ratings, Dragoons Rating, etc) is counter intuitive to what most folks would be familiar with.
What I mean is that under the current Strategic Operations Tables, A is the worst (Salvage) while F is the best (Excellent). Typically, things graded as A are considered excellent, while things graded F are considered awful. I believe that the change in scale creates unnecessary confusion without adding anything to the game other than reversing the ratings. While this is a minor issue, I hope that others might agree and that this might be reversed back in the next printing/future editions.
Thank you for an excellent product.
