OK so if you don't belong to a particular GC, you can still access the Quartermaster menu and view the available gear, and use the 'try on' function still.
However, you cannot access and view the new Allied gear from the Huntmaster unless you belong to that GC.
Aesthetics are an important factor for a lot of players, choosing to switch GC boils down to which gear i prefer :) can we have this implemented at some point please?
