The recent Rising Death fix (Shadow Piercer Upgrade)

The latest patch notes say:

Shadow Piercer’s “Rising Death” initial impact damage is now on par with un-upgraded Shadow Piercer

Does anyone have any ideas about what this means? Does it make it worth it to train Rising Death? I had it trained on my Rogue at one time, but didn't notice it doing anything worth noting. Does this mean it will do enough damage that it would be worth training again?

Prior to this patch, rising death actually reduced initial impact damage (which is why rising death was generally viewed as a silly upgrade).

Now, you don't lose impact damage, so the net effect is that overall damage increases, but the multiple-hits from rising death are small and there are better places to spend a skill point that would be more effective.
