Claiming Rokugan is a great setting for Oriental flavor is like calling General Tso's Chicken authentic Chinese food. AEG has completely watered down the societal and moral constructions that make feudal Japan fascinating. Admittedly, I'm somewhat biased as I have a significant background in Asian history, but still.
This thread seems rife with misconceptions about just about every published campaign setting. Eberron is neither high magic, nor high powered. There's a widespread use of low level magic, but the really potent stuff is by and large out of reach. Furthermore, most of the world is composed of low level characters, with only the examplars of the forces of evil standing as the high powered characters (The Lords of Dust, the Inspired, etc. al)
Also, I don't know where someone is getting the idea that Forgotten Realms adventures assume 32 point buy characters loaded down with magical items and capable of destroying their foes with eye lasers. Seems like just another person reading.
From my reading, it seems like the OP has disqualified just about anything offered to them.
My only real suggestion is Midnight, since it still features magic use (at a much curtailed level) and requires the players to really think and exercise caution in dealing with the world. Of course, it won't appeal to people who just want to kill things and take stuff, or characters with delusions of grandeur.
