So after actually playing with the changes to DRK. I was trying to give it benefit of the doubt but....I hate it.

Plunge change I can stomach, but both the Blood Weapon and Living Shadow are straight up downgrades to the class made for no reason. Living Shadow lost its only tie to the rest of the kit that was its cost, so now it's just empty button to press. Blood Weapon losing 2 stacks means our mana economy is worse, both making the problem of everything outside of 2 minutes being non-rotation worse, and it makes TBN feel worse to press, which just...awful.
And all we got in return is this lousy GCD. Thanks, I hate it.

Give BW its 2 stacks back, increase the MP gain on the 3 stacks it has, hell, reduce CD on Delirium to 40 seconds....anything. The other tanks are at worst the same as they were before, or slightly better, only DRK just got...worse.
