Yeah the normalization is true, so its not "just like the Cudgel O Pain", however it is normalized to your weapon speed and not your CA casting time. This may be modified at some point but for a class that has a lot of fast casting or multiple attack CAs they don't suck IMO. For example it proc's on the interrupt on a swash offensive stance and multiple attack CA's like Whirl of Blades and Uncanny Response. Each hit is 10 damage with a 2.5s delay weapon (if the mob isn't debuffed for that particular type of damage).

For just the weapon damage it isn't so impressive. When you consider how it affects all CAs it doesn't suck. Hmm maybe I should go dust off my bruiser and play around with this, like back when Illusionist+Bruiser was proc heaven.
The description of these items is too vague to tell if this was intended or not.
Still not impressive for priests etc, but great for scouts and probably brawlers. But if you are tanking you'll likely have the 2% riposte adorn or something else.
