Display Titles under Character Names?

You can't actually buy and sell titles. Unless you mean like selling HM/EX Primal Wins. In which case it would be a LOT harder and more tedious to the point where no one would be willing to sell, or if they did, it'd sell for the tens of millions if not hundreds of millions. Well, either that, or it's an event title that's so easy, anyone can earn it by themselves.

FYI, people have been selling XM Primals since week 1 of the patch. These same groups sell 3 spots in HM Primals as well.
