just think of those pants items as free upgrades -^.^-
you should get at least ONE usefull upgrade, unless your vary unlucky, and since it has 3 types of class skills, who is to say they arent there soley for the purpose of salvage for parts?
you have 4 things you can get from it, right? ether 3 different class upgrade, or materials.
so just salvage em, and think of them as a 3 way upgrade chance, and hey, if its pants, you wont feel bad for salvaging it for its possible upgrade
