Disclaimer - I don't fly and haven't flown the bus.
However, abnormal attitude law does seem to be a big issue in general to me. As I understand it, bus drivers only ever touch the trim wheel to set trim for takeoff.
Therefore a law that:
- (after an upset has occurred!) freezes the trim in a position that may have contributed to the initial upset
- expects pilots in an upset to recognise and comprehend this law degradation
- expects pilots to trim manually to assist recovery, despite never trimming manually in normal ops
In my opinion has serious issues. In general, the concept of being trained out of the need to trim is in my view inherently detrimental to the skills required for upset recovery.
