I feel like the season finale fell really flat. None of the issues have been resolved and there really wasn't a shocking revelation at the end that put that wow factor going into the expac like when it was revealed that the Sylvari were dragonspawn.
I'm still hyped for the expac, but damn the last ep was disappointing overall.
On the flip side, the new fractal is spectacular. But I bet everyone will avoid it after a while. Its longer than Cliffside, and you can't just run through it because it consists mostly of 3 somewhat lengthy boss fights. There is a cool low gravity area with some jumps and some neat puzzles that introduce you to some of the new mechanics before you need to use them, I can see people raging in higher tiers when people get lost in these areas.
