I would personally like to see the old EXP-boosting gear re-released as replicas, particularly the Baron set.

I would also appreciate some way of trading in the 'genuine' Manderville earrings (which I bought from the Rising event) for the replica ones. They're level 1 instead of 20 and actually more useful, because you can glamour them onto the aetheryte earring - and you're not going to be wearing anything else all the way to Lv70 if you have it.
