Just started to get rare gear on the Kensei, and to my disappointment, found out that rare gear can only use other rare gear to customise its appearance. Really think that the appearance changing shouldn't be limited in such a way, as all the rare gear I have gotten so far is covered in gold, which is obnoxious and ugly in my opinion. So much so that I don't use said gear. I know you can get rare quality versions of the standard gear, however, with the increasing amount of gear variation the higher you get, the chances of you receiving those pieces diminishes.
