I love that we finally have Genasi.

The only thing I think is missing is that the Earth and Air Genasi don't get any cantrips, when the features they do have aren't really much more powerful than Fire/Water. Personally, I'd give Gust to Air Genasi, and Mold Earth to Earth Genasi. That'd put them more on par with Fire/Water. And possibly allow players to choose between Control Flames and Conjure Flame for Fire genasi.

More fluff is better. Air Genasi even have the fluff text about being accompanied by minor gusts of air all the time.
