If this happens Im sure it will be in 2.0 and hopefully they are already working on something like this. Also Im pretty sure there was a similar thread to this one a long time ago, but ti cant remember.
At night I would love to see some fog with random enemy encounters like old school rpgs. It used to be you walked for a couple seconds then bang, fight scene. I would love to just be walking and have wights/skeletons crawl up from underground and attack you at night, add some fog and eerie music too.
I remember when i first started playing ff14 and it started getting dark and i was like "oh, i wonder whats gonna happen" haha, yea, nothing happened.
EDIT: I know 2.0 will have different themed zones, so I would like to see each zone have its own version of night time, with different mob themes.
Need more torches
