I tried the new fractal today. The first part is using a toolkit to make your way down/across a chasm. 4 people need to stand in a circle at the end of several difficult parachute and grappling hook sections, so I forsee that being annoying for a while. We tried the boss for about an hour. It has interesting mechanics, but it's very difficult. At 66% and 33% you have to split and cc a mob and kill it before the boss did a big aoe. We didn't make it much passed the 33% split.
