Renly's Training Warbringer Node

I think the Renly's Training Warbringer Node doesn't work as intended. It ignores the incresed block chance modifier on the shield. I have a shield with a base block chance of 26% and 75% inc block chance mod which gives my shield a 45% block chance.
Renly's Training says that the shields base block chance is 40%. When I spec into it I lose block chance.

+1 same Problem.

The shield is set on 40% Block and ignores increased Block chance prefix.

Bumping this, but I'm honestly not sure if its intended or not. The wording of the ascendancy makes it seem as if the increased block chance prefix would apply after the base block chance of the shield is set to 40%.

Yea, me too. That's rather frustrating because the entire ascendancy node is effectively as good as one modifier line on a shield with the exception of if you specifically use a unique shield.

+1, complete garbage ascendancy point if it's supposed to be this way
