Savage Melee as a beta powerset was clearly unfinished. It would be great to bring some consistency to its ability animations. As someone who plays a lot for the feel of using abilities, it makes the character pretty unplayable at the moment. There are three components that are currently out of sync for many of the abilities. The character animation, the power FX on the character and enemies, and the resulting damage ticks on enemies. The animation is likely the hardest to change, and the damage ticks are the only change that would have balance implications.
I have only seen up to the level 8 Rending Flurry ability so far but it is the worst offender, playing the Flurry FX on enemies which doesn’t match the animation, and doing only one tick of damage. I have also been told that the Savage Leap power has these issues. I will reply to this to add specifics when I get a chance.
