MoP Buff Questions

This blog goes over current designs in MoP in terms of buff.

But this leaves a few questions myself and probably many others have.

So i'll start.

8% spell damage debuff:
It looks like druids lost earth and moon. I think reducing the classes that can do 8% spell damage is going to hurt 10 mans. Is this just a missed mistake or is it actually gone?

+5 Mastery:
This seems OP. For certain classes, missing this one could be quite significant no? Will this not also force the base mastery to be lowered for a few if class design is designed around this buff existing?

melee and spell haste:
These being separate is still one i'm always conflicted with. Can't these be combined yet? Seems redundant at this point. The crits were combined in Cata.
