Shadow priest in alpha/beta

Hey anyone have opinions on the changes to shadow in the alpha/beta I saw what looks to be like nerfs and loses on talents/abilities and are wondering if they are going to be in a bad state for the next expansion. I recently got mine to 110 and after seeing the changes am wondering if I made a bad choice and should have went for an affliction lock instead. Before I get too anxious about the changes I want to know what people think that have played it with the new changes and how they feel it stacks up against the current live build in legion
