As title suggest the lvl50 Set's are currently able to be stored in the Armorie but for what ever reason the lvl60 and 70 sets cannot be stored. These sets take up a SIZABLE amount of space in my retainers and even though were able to store event and seasonal items in the armorie the artifact sets beyond the original lvl50 ones cannot.

Currently we have only 200 slots in the Glamour Dresser and this can easily become filled with other nice things not to mention storing the artifact sets there actually uses up pretty much all the space but the Artifact sets are something that should be able to stored in the armorie as they're artifacts not dungeon drops or craftables. :/
