It's about the music...

I think personally the best OST for any online game would have to be Everquest 2.

I disagree. Everquest 2 was boring in many places, and this whole game feels like a better version of that (and no, I'm not an FF fanboi or an SE White Knight - this is my personal unbiased opinion).

In all honesty, there's a good number of songs that make this game awesome, but they don't always play for very long. Haukke Manor anyone? We got Castlevania up in dis bish.
