Also for rogue splashes (with the intend to be a trapmonkey) a human is a good pick. For clerics/fvs the extra +1 wisdom is also not that bad.
You're correct the things that speak for a human are the base rules, I doubt they offer any useful enhancements.
Isn't this the DnD idea of the human? Can do everything pretty well, but for nothing the core specialists race?but there is no defining factor on a human which screams "THIS CLASS" human is great.
Edit: Above it reads "Human The most adaptable, flexible and ambitious of the Eberron races."
I don't see the ambitiousness reflected anywhere, would be a nice place for an improvement
