Not a fan of TCW/Rebels, but Traviss' work is just as bad. I mean, it's just utterly laughable how overpowered she makes the Mandalorians in LOTF. Two random Mandalorians nearly kill Jacen in Revelation, Tahiri gets outright destroyed by random Mandalorians, the superb uber Mandalorians single handedly beat back anything the Vong threw at them, and after about two Chapters in Sacrifice the entire galaxy is scared of Mandalore because reasons.
If that's not favoritism, I don't know what is.
