There are a lot of bg and wl sets in game already some people have both and they are the only somewhat valuable and desired sets ingame other than bd which is a classic. Reintroducing them for even a day with the myxx elixir will make them worth less than the prize vendor vanities because those require plat to be bought and dont return (considering tradable ones). Once they are back you will get yourself one of those and a week later you will be like “well everyone has it and its cheap i had fun with it but im now bored” so in my opinion they should stay where they are and stay as desirable vanities to farm gold towards.

And im pretty sure people would be more interested in farming new stuff other than old ones being introduced over and over again right? A lot of good suggestions are in the official thread so i think we should be supporting those instead.
