Well, I personnaly would like it if the weather itself had physical/mental effects on the characters using the gods...

for example if we choice a god with the water nature (we get a small boost during Rain/ or water related weather..

Also .. Personally id like the environment to show us the fish we catch instead of a white light lol ... and for the love that is all unholy.. Bring back ffxi fisher guild npc that you could sell fish to for gil... (like seriosely)
