My thoughts on the nerfs:
Hardest hit is murloc paladin. Murloc Warleader change hurts murloc paladin quite a bit, the semi-heal was so useful and was often just enough that the murlocs stayed alive. They've been way off the power scale for a long time now (can you imagine not teching them in with any current murloc deck?), so i guess they needed to be nerfed?
Aggro druid getting a slight nerf. Innervate/hydra and Innervate/Flappy bird were semi-win conditions, and it will be much harder to buff your minions without innervate. That said more low cost minions will replace innervate so the deck gets to be more consistent. Expecting nerf won't hit aggro druid too hard.
Fiery War Axe has been fringe in pirate warrior, like people said this hurts control warrior much more than it hurts pirate. Expecting pirate warrior to be just as rampant.
Hex has been fringe for shamans and like the fiery war axe change, this really hurts control shaman (which doesn't exist) more than anything.
Spreading Plague nerf doesn't hurt jade that much imo and it will remain the number one deck
TL;DR: Meta won't change beyond murloc paladins being dead
