Just finished this, damn this is a tough one. I found it very interesting that 1 hour isn't just a random number that looks pretty, its actually a threshold that's very hard to hit and requires a good deal of coordination, speed, and luck. All of our failed attempts were only 2-5 minutes short, and as far as I'm aware the fastest run is around 55 minutes. I can only see EU leaderboards where we took 49th place, how many have completed this on US, for comparison? As for class balance, DHs are obviously the most popular for this, with wizard and crusader closely behind. As wizard I was slower than DHs in most areas, but in some (mostly act 3 ramparts/depths/bridge) I had an advantage due to being able to skip walls. Not sure how crusaders perform, I guess they should be very similar to DHs on this. Monks should be slower since they can't quite achieve 0 cd blink, but they do have high movement speed to compensate. I have no idea how a few WDs got in there.
