You shouldn't be allowed to purchase a job skip until you have Lv50 in that role. I often get skippers who are completely incapable of playing their role in dutyfinder with any level of competence. Skippers are also the ones who invariably have major attitude problems, such as screaming at people for "stealing aggro" and having usual the "sit down until you kick me" tantrum when called out on their obvious inexperience.
