If pilots only hand flew 1% of landings, they wouldn't be sufficiently practised to do a good job. The simulator just can't recreate real world conditions accurately enough to be relied on totally.

Hence, pilots must fly a certain number of manual and auto landings in a quarter to stay legal.

Exactly. A contributing cause of AF447 was a lack of high altitude flying experience and training on emergencies there, since the training regime is traditionally focused on the more accident-prone takeoff and landing phases.
