I really dislike the independent progression system. The last thing I want after weeks/months (whatever it is) of obtaining my gear is for it to become worthless. This works in both ways, gear I've worked hard to obtain will be negligible in there, and progress I work hard to obtain there will be negligible outside of it. To me, this makes this content a pass.

We'll see how it goes though, it may be a fun. Though in all honesty, I play an MMO to keep my progression of my character.

On a side note, this seems a lot like Fractal of the Mists from GW2
