These changes are horrible. Shad Priests are now a hybrid of what Affliction Locks and Destro Locks once were. Maintaining 2 dots with a channeled spell you have to constantly clip due to random MB Procs and DP uses. I feel like I'm all over the place with any sort of rotation. I know rotations tend to make us tunnel but without any fluidity in a class/spec, it just isn't good for business.
I raided a rogue for 2 years while having this desire to be a Shadow Priest. I finally made one in the middle of Wrath and had a blast raiding one for the past 3 years, but I'm sad to say that my Affliction Lock is looking better each day.
