Is it just me or does it seem like the only reason why we're finally getting Lesnar back is because there is a possibility of backlash over the new RTWM being limited to only 3 characters?
Don't see why there would be backlash over only having 3 superstars in RTWM this year. Doubt most people really care, Just are happy that its longer.
Also just read it again and I think you can choose the option to be anyone not just a CAW.
Playing through the second arc will lead you to the most customizable portion of the single-player storyline - the third and final act allows you to select or create a custom superstar, who will run through an "outsider" storyline.
