I would like to make a suggestion and it's that I think seasons would be an incredible addition to this already great game, having Winter, Spring, Summer and Fall affecting Eorzea would make it so much better, you could make it so that each season lasted for an entire month (Earth time)!.
I just would love to see Central Shroud covered in snow and I don't mean anything like when Odin appears but like Cohertas itself, also it would be awesome to see all other regions in different seasons, it would make the experience so much more dynamic!.
I hope you can make this simple wish a reality sooner rather than later!...
