I have a LOT of main story to get caught up on, what I wanted to ask is this:

Should I bother doing it now, or could I just do it on gunbreaker/dancer? I don't believe these are locked behind the story but I was wondering others opinions on it.

I am to hyped about Gunbreaker so I'm not really getting into any other jobs right now. Would I miss a lot of the experience of a xpack launch (I was there for SB launch) or might it better to do the story on Gunbreaker so I can avoid the mass of initial players?
