I believe this to be a non-issue in all honesty. while the Stage 10 GC earring doesnt work for DB it doesnt mean that you cant use the GC accessories that TT offers currently and i'm sure you can find a few TT runs willing to not price gouging new players. Even then 200g for them isnt all that hard to come by now. I recommend sending those accessory boxes from CTA to another character and be glad you're somewhat able to gear another character through CTA.
