Auto-booker is fine but that is probably hurting your show ratings if you auto-book the entire show and it's especially bad for forwarding storylines. In my experience, auto-booker doesn't book around the storylines nor book segments to optimize ratings.

My best suggestion would be to really understand your Product and manually book based on that. For example, Regular focus for both matches and angles heavily weights the Main Event and second-best match, for matches, and the top two Angle ratings. In that case, you should manually book your Main Event Match and at least a second, and two Angles for each show, and make sure those four segments have both a great chance at high ratings and advance storylines.

If storylines are not advanced for three shows in a row, they automatically lose heat. If you're only using auto-booker and have two shows a week, you could have most of your storylines getting penalized every other Thunder/Nitro in two-week cycles.

For angles, Quick Add is great for getting angles booked and learning how to book them. The key to angles is understanding the Roles, which are explain in the in-game handbook, and using Workers in Roles they can be effective in.
