I love the way the new system deals with rings, skills, and approaches. Every ring is potentially useful for every skill. No longer must every katana-wielding bushi have high fire/agility. Also, the fact that in 4e, virtually every social skill was governed by awareness was one of the great weaknesses of that system. It led to the proliferation of high-air duelist/archer/seductresses.
Now every ring is potentially useful for every skill, but there's still an incentive to diversify rings, and a disincentive to overly specialize.
Also, I love how there are multiple forms of intelligence (memory, creativity, cunning etc) so it isn't "inefficient" to make my scholarly character anything other than agile.
Overall, it's a very elegant system that captures the spirit of the setting.
