Agree 100%! What's crazy is that DC has some of the earliest black heroes in comics and yet, they lack a rich publication history. Vixen in particular is one of my favorite female heroes and member of the League but, why is she excluded from recent League lineups? Bumblebee has increased popularity thanks to Super Hero Girls and Teen Titans cartoons but, is seldom used in the comics. Why not use the popularity from other media to draw her fans into the comics? Feel like DC's black legacy heroes are such a missed opportunity. There are great characters which have enjoyed popularity in other media that just aren't being used.
Speaking of Vixen, during Orlando's WW run, there was a mention of Donna and Vixen's friendship. I would totally buy a book where Donna and Vixen team-up! How about Donna leading an all-female team of Titans featuring Bumblebee, Steel, Miss Martian, Raven, Starfire, and others?
