Bit of a selfish ask, Do you think 6.0 zones will return to the high fantasy of HW's?

What's stopping them from spreading those 10 levels across 12 smaller maps?

The amount of MSQ. Unless you want the MSQ to be unnecessarily long, there would be even less to do in each zone.

Also, some people want to reduce the amount of load screen required to go places.
