I found that mechanic during the last fight very interesting, charging the pylons and then shooting with the main crystal. Flying over kralk was fricking awesome. I like his new model. I would have maybe made a longer fight with 2-3 more crystals. Or climbing on the back of kralk to destroy some of his scales. But the current is more than awesome don't get me wrong.
Even those dragonblood spears are cool it gave me some memories from lord of the rings/the hobbit.
