Perhaps they could at least relax the restrictions on obsolete gear? Job-specific sets can have a flag that they can't be glamoured cross-class, and the newest gear can have that too, but a lot of the old junk gear is never used by anyone any more (especially the harder-to-obtain stuff around level 50 where you get a massive amount of pieces available except it's quickly rendered pointless when you start picking up 3.0 pieces with better stats). Just let people have fun and glamour it.
