I have a thought of adding some kind of Fame/Reputation System

Basically, every achievement that done in particular region(La Noscea/Thanalan etc) will rewards player of Reputation point (of that region).

What can we do with that reputation? my ideas:
-After certain points, NPC will give you discount for items/ticket(discount 10% for 3000 points)
-There will be rank for the reputation such as "Adventurer of La Noscea"(0-100)/"La Noscea Landlord(5000- )" or something like those
-We can trade those points to gameplay convenience such as:anima point(trade 10 for 1) or guardian aspect buff(trade 15 for 1)

How do we gain reputation:
-every leves that done in that region add small number of it(maybe 1)
-doing sidequest (maybe add 5)
-Participating on NM fights (maybe add 25)
-Synth +2/+3 items

Any reducement? well maybe death will reduce 10 points.

so, is it interesting or not?
