A kind of similar question popped up in my head today as well.
It's about the item codes from the 1.0 versions; I still haven't used them because my character was already high-lvl until I realized I have to put the item code in BEFORE creating the character.
So I've been keeping them for the time when I make a 2nd character which is at the beginning of 2.0...but will we be able to use those codes in ARR?
Please don't destroy my dream of a Garlond goggle Viera and a onion knight lalafell, SE :x
