I agree about not re-release the old lb vanities (at least not doing it in a random contest).
I would love to have those vanities back in the game, since there are very few of them left, and if they are ever reintroduced a fair way to obtain them would be in a whole new event as lb prizes but this time make them nontradeable, try to make this event a whole-vanity-focused event for more info of this idea I'll make a post on the suggestions and feedback section
