An interesting development.
According to
this post that was just made by GC 15 mins ago, it seems like there are
massive buffs coming for almost all classes.
While not directly mage related, I do think this is telling. It seems like the massive buffs to other classes coupled with the Arcane nerf could mean the 'hypothesis' of Arcane's demise is actually looking a LOT more likely now.
What I do find interesting, is that there is no mention of Affliction nerfs. So it seems a lot of other specs are being brought up by a very significant margin, Affliction is being left where it is, Arcane is (as we can see) being nerfed hard.
I'm not quite sure wtf is going on at Blizz HQ, but I think the interns might have taken over. Either that, or there is some timewarp effect that has sent me to April 1st.
