Total Divas is a pretty good promo indicator.
Playing a character well in a 10 seconds TV appearance is not enough to qualify as a proper manager.
Total Divas is a reality show that exaggerates real life behavior. That's the last thing I'd use as an example to judge her skills of doing a wrestling promo. Her backstage stuff though shows me she could talk very well and be Sassy and all that like she was ment to. Anyway to each their own.
I hope Cameron goes some where else and improve in all areas.
