I'm sad at how bad Control Shaman is now. I can't even get it to 50% and all I usually do is play control shaman. Jade sucks, N'Zoth sucks, Crusher sucks, Elemental sucks. They all suck. There's no way to ever gain initative before dieing, because all the stall tools leave you with a chain of overload to always be behind tempo.
It's really annoying that they chose right now to nerf Hex. I totally agree that card deserved the nerf, but why right now? Why not wait for the next expansion where you can also buff the archetype? I guess because it's not meta right now means it's ok to screw over those of us that like to play it even when it's not meta? That makes no sense.
Hex is now probably slightly worse than polymorph and for this particular meta neither are worth playing in any deck. You're not really gaining any ground using it on a 5/5 which already buffed a minion or made your hero power cost 0.
It would probably be playable if Healing Wave and Elemental Destruction were still standard. Healing wave lets you stall a turn for only 3 mana and no overload. Elemental Destruction let you have enough mana left over to actually create a big swing turn that might take them two turns to deal with, unlike something like Volcano which usually doesn't leave you enough mana to do anything meaningful on the same turn, while also making your next turn weaker.
You can play it in wild but wild also has a lot bigger power level overall to go against, and there's not really anything it can do vs giants.
