So, my being the overachieving chango that I m, have mastered all 5 classes.
The only class that has awarded a clearly defined Mastery outfit/helmet, is the Demolitionist.

I do not have the mastery outfit for Guardian. (My starter class.)
I do not have my Combat Medic Mastery outfit.
I do not have the Assassin Master outfit.
Or even the Assault Outfit.
Or the headgear for any of them.

Also looking through my gear I have the Frontier EMT set.
I have the Demolitionist basic set.

However, the other three basic sets are missing in action.

------------------

I have other issues as well. :P But I am keeping them separate.
