The Custom Playbooks are so buggy this year, I haven't been able to test the Custom route with update 1.10, yet.
I would assume they weren't touched because None of the developers have mentioned this as an issue yet.
With that said,
I've had good results with,
Generic PB's (Run N Gun, Pass, Balanced, run balanced, etc)
Defensive PB's(Multiple D for 4-3 teams)
