Yeah and that. 7.1.5 made Vulnerable a bit more rewarding to play into but the spec (entire class imo) is still a far cry from being the best it has ever been. They tried to reinvent the wheel but in doing so they deflated the already existing wheels...
And the worst part is that it wouldn't surprise me if they repeat it all over again with the next expansion... What is it that makes them want to rebuild the classes with every expansion anyways?
