Affli is not getting nerfed with these hotfixes. If you're referring to the nerfs from months ago, arms also got nerfed then and those are irrelevant with respect to the current discussion -- we're talking about what "should" be nerfed now.
I don't think any spec, ever, should receive a 9-10% nerf mid-tier. It's ridiculous. We can sit here and say sure, Arms will be "OK" or "deserved" a nerf mid-tier, then you also have to apply that logic to the specs performing as well as if not "better" than Arms. Of course that's all subjective, but the logs consistently show 5 specs overperforming compared to the lower clusters -- boomy, arms, affli, spriest, and sub. Arms got a large nerf today. Sub got a smaller nerf today. The other three made out like bandits today.
We can keep this charade going I guess where you just quote me saying X doesn't need a nerf, and I quote you explaining how A, B, C, D, and E probably need nerfs, but the timing is poor. Legendary nerfs like this should have happened pre-TOS, PTR, before any aura tweaking went out. Very poor timing for mid-tier.
tldr: The nerfs themselves might be "fine", but the timing and sequence of nerfs (aura nerfs early on AND THEN legendary nerfs) is extremely poor.
