I am OK with this change. I had a couple nights of fun totally destroying the meters. Spamming SW: D didn't feel right. I loved the idea that our rotation and gameplay changed so much during the Execute Phase, and am very sorry to see it gone tbh.
However, SW: D should not be our main damage dealer. It should not do more damage overall then Mind Flay. It is wrong, and frankly, how Blizzard would create such a glpyh for Shadow Priests is beyond me. Surely they must have thought we would gladly abuse such a DPS increase?!
I am yet to do my own testing, but it does appear to me that we are once again back to the same old rotation. I'm wondering if it is even worth having the SW: D Glpyh now, and I might revert it to SW: P since I don't need the Dispersion Glyph anymore.
Dissapointing overall methinks, but very much needed. I do feel they could do something with our class though, I thoroughly enjoyed the changes, weaving in SW: D, making conscious decisions on whether to use SW: D or MB it was innovative and fun.
And I of course enjoyed taking my guild to town and showing them proper numbers
