I miss the 1.x weather effects too. Also the nights were much darker. If I lived in Eorzea now I'd go insane because it's never dark I'd never be able to sleep!

I'd love to see darker nights and characters using handheld or holstered lanterns to light the way. Animations to pull up a hood (if your armor has one) in a rain/sandstorm. Small things to make the game more immersive than just "things are happening around me but don't affect me in any way".
