I think the guy who handles lock simcraft was gonna try to get some numbers out to us this weekend. I also personally don't feel the sky is falling just yet. While this is a definite nerf to our cleave damage it's not a nerf to AoE and only a very very minor nerf to our single target dps. GoSac does not buff FnB and so on fights with lots of AoE I don't see whats wrong with going GoSuP/Obs. So, long as we have enough crit on our gear to keep up embers, for our now increased haste, while we FnB like crazy I don't see the problem. (Note - I know it looks like demo may very well be better than destro at those 2 things and so destro may not have a niche its top but until we get some type of math to confirm this without doing napkin math based on T14 sims it may be a bit early to declare the spec dead)
