That´s a bit unfair. In Bess/Ben´s case she/he is an infinitely changing blob. I´m pretty sure the artist is allowed some freedom in such a case. And most of the time Adjatha draws myr and New Texans. And they are supposed to be pretty comic-ish.I'm still quite sure than indulging own fetishes instead of following character description is a bold sign of total incompetence for the illustrator.
I´ve also seen more normal looking characters been drawn by Adjatha, so I don´t really think he/she (I have no idea) can be described as an incompetent illustrator.
But I don´t really disagree with you regarding locking bust artists. Some people might f. ex. just want Chesire busts.
I however enjoy all the artists
So I wouldn´t really use such a future myself
