The Roar is my favorite area in the seas, it has such a unique harsh character that sets it apart from the other regions. I love playing there, some of the best, most memorable encounters I've had with other players I've had in the Roar.
I would like more updates to that area but I think Rare has a lot of things on their plate right now and I think it will be some time before their attention turns again to the Roar and it's potential.
That being said, I have come to hate the geysers, the darn things are so loud they give you a headache. I believe if the geysers were toned down and the noise impact was lessened somewhat, more people would enjoy playing in the Roar. The volcanoes are manageable but the geysers are relentless to the point of just being actually painful and annoying. So I'd like to see an update which would make geysers more bearable.
