I wouldn't give it a 9/10.. it's really nice to see but the fog even with all you can have to reduce it starts to annoy my team... for example yesterday we spent around 30 minutes just to find a dungeon as they are really hard to find with this fog but we didn't find any black core inside so, disappointed, we stopped playing
I like the idea of the fog but we would really appreciate an enhanced version of the wisp torch
