I didn't give the article an extensive read, but I like it myself. The idea of Genasi as a race in its own right, as opposed to half-breeds, appeals to me for some reason...I never liked that the Planetouched races of 3ed were set stats rather than Templates...

I like that a Genasi can manifest more than 1 aspect as well...that's just cool! I'm not sure about the Storm 'element' though...I've always kind of imagined 'storm' as being the combination of all four classical elements; so a Genasi that can manifest Fire, Earth, Air and Water could then have the ability to manifest Storm as a combination of all 4...might just be me...
