In my opinion, the current quest shaman decks are trying to hard for value, I think that the best variants will be the aggro ones. just go face with all the burn and then finish with shuderwock if necessary.
I don't know about that. I'm at 68% win rate with my quest shaman at rank 7 and currently crushing those decks except for murloc paladin which is quite difficult. I think it depends on the decklists people are using and knowing when to play a tempo or a control game.
It's completely stupid to try to look at winrates for quest shaman. There's a million different ways of building it. Ultra aggro, midrange, value, ultra control/fatigue... From the decks you listed, I crush Control Warrior and Quest Druid pretty hard. Murlocs decks are fine. Quest Paladin depends on my discoveries : I had games where I discover bunch of hexes/plague of murlocs and they can't do anything. I also had games where I discovered nothing and just went full burn / face gameplan.
Quest Shaman is going to be a deck that needs a lot of refinement. Quest Druid is braindead to build for 90% of its cards, so is Control Warrior and Murloc decks. Of course they are more refined right now, doesn't mean that they're better.
And maybe they will (be better), all I'm saying is don't judge Quest Shaman too fast.
And for the record, I'm stable at 300-400 legend with my Quest Bomb Shaman. Since it's very control oriented it's hard to refine it yet because people are playing a lot of different decks still, but when the meta will settle down it will be easier to figure out what should be in the deck. I mean, when you face a Paladin that play King Phoresis on turn 5 with a full board you're wondering wtf is going on ladder.
The problem with it in a control deck is... do you really want to not run Hagatha? I almost wonder if there's a world in which you'd run both, like how Baku Mage used to sometimes run Frost Lich Jaina. At a certain point, you can hero power + Hagatha for a 6 damage AOE clear and switch over to spell generation.
As someone who has been playing Control Shaman for the last few months, Hagatha isn't as reliable as most people think. Sure she gets value, but the randomness gets bad quickly, and Shaman got some really shitty Spells. At least with double battlecries you know what you're getting, making it beter in my opinion. Maybe both can indeed be run, but lets have some fun for now, with the new cards ;-)
I've been thinking about Barista and Earthquakes and the likes, so not yet sure about an optimized list.
It’s one of the most versatile to build around. Lumping every quest shaman in one deck is a terrible way to track it. Personally my lackey zoo is my most successful. Control hasn’t been great but there’s a lot to refine I think. Going to tech around the meta soon and retry. Try different builds, but if you can’t win against anything it might be playing poorly in a new meta.
