But did anyone play as Voidwalker in the live demos? (Destiny)

It looks to be much more flexible than Bladedancer. With Bladedancer you are limited to single target impacts, and you move with erratic dashes and lateral aerial attacks as a primary function. While Arcrunner appears to have more sweeping attacks that don't seem limited to single targets, as well as a more aggressive aerial smash.

I think it is all a case of replacing the least viable/flexible subclasses, relative to the changes to sandbox. Shifting everything to roaming supers means that Defender needed a full revamp, so Sentinel. Changes to the general power of abilities (sticky grenades and melee power) means that Sunsinger needed an actual core capability. And Bladedancer ancer was basically, in my experience, not worth popping your super except to clear adds poorly and PvP use is to be erratic and auto-aimed melees.
