The end chest also dropped bizarrely good equipment. For example I got an earring with +25 to all stats, +3 CD, +3 MF and an unused upgrade slot. I also got the previously mentioned 20 slot box and several exotics.
It's hard to tell how much I was bribed, but I personally really enjoyed the finale. It was long, but once I realized it was going to be hella long I just relaxed and enjoyed it. The river of karka hatchlings on the spiral was one of the coolest things I've seen in GW2.
