Why aren't the developers taking advantage of the leve system?

I just wish at level 50 EVERY quest converted total XP into a % of Gil instead, so that the only reward you got for doing ANY quest was Gil.

Tread lightly, this is a mechanic used in WoW, many people will look right through the idea, no matter how good it is, and only see WoW. Also burn a class to 50, then run around doing all the quests would make for easy gil, and they would say that it catered to RMTs, so the gil reward would be reduced to something that wasn't really worthwhile.
