There is no hope, lol.
We have been telling them since last december that they were smoking something really bad whenever they came up with STM. But nope "it's fun to see a shadowpriest fight its own death LOL CLASS FANTASY".
We have been telling everyone and the devs that STM is so powerful, the whole spec is going to suffer from it. But nope "OMG stfu you scrub, you don't know what you are talking about !!!!!!!!!!! It's okay if shadows suck at everything in the game if we are good at some fights with STM !!!! GO DIE PLS" - from "top" SPriests. (when I say "top" i mean those proclaimed hardcore proskilled SPriests that can never show logs to prove their claims.)
We have been given them TONS of ideas and way to fix shadows during all the alpha and all the beta, the shadowpriest thread was the BIGGEST thread on the beta board => no answer from the devs, they didn't listen.
They did listen to high ranked (arena) druids when they cried that shadow was too strong so they nerfed shadow in pvp. That's something :')
So yeah, sorry but hope will come back when STM will go away.

And when you see the amount of people who saw the "mind sear damage increased by 50%" and thought "wow, SP got buffed so hard !" you understand that hope is forever gone.
