Here's the video discussing the Balance Changes, starting at 1hr 6 min. h ttps://www.twitch.tv/videos/402688127
The gist (all subject to change):
Snares significantly reduced
Snipe gets minor defile instead of major, 1 second cast time, reduced damage
Steel Tornado's execute is given to Whirling Blades instead
Molten Whip becomes a burst damage skill. Using Ardent Flame abilities will grant a charge that increase spell damage and a % damage boost to your next Molten Whip, stacking up to 2 or 3 times with the stacks consumed when Molten Whip is cast.
Wing's reflect is changed, now reducing damage taken from projectiles by 50% with no target cap, thus lasting the full duration. Dragon Fire Scale now fires flame projectiles at attackers once per second similar to Flames of Oblivion.
Jabs has been brought in line with the GCD, same damage just shorter animation
Valkyn Skoria now has the same audio cue and visual telegraph as Meteor, in a different color
Bird of Prey (and possibly the other morph as well) had its major expedition cost reduced
