The new talent system is actually really good. Because now, instead of of just picking the standard spec that everyone else picks until it is changed and then you pick everything else that everyone picks after that, you can pick a move or perk that fits your playstyle.
First time I listened to this BGM is in Twilight Highlands. There is a river called... I don't know the name because I was playing Chinese Edition. But I think the name would like "Walaer" or something else. I just listened to the song on that river.
