i think you have a problem with beeing nostalgic.
you call something good when in reality it was annoying.

CRPGs are not known for their realism or their world simulation.

small unconnected maps are fine for stuff like FFT. in CRPGs they ofthen mean loadscreens.

The only way i would enjoy this if it were like NWN2s second expansion that actually had an overland map and as a result gave rangers something to do.
Traveling on a map between small bite sized maps simply so your immersion isnt ruined is ridiculous.
