This was actually the primary weakness of Jade Druid before Knights of the Frozen Throne. Then Spreading Plague made it possible for Jade Druid to stall long enough.
I play a lot of Jade Druid and my big swing turns are when I Spreading Plague a board with 4 minions then MC Tech or Swipe. This usually gives me 2 turns to develop more Jades behind it.
Jade Druid doesn't use Auctioneer anymore since Ultimate Infestation was printed. The two decks that currently use Auctioneer are Miracle Rogue (overall worse than Tempo Rogue) and some variations of Razakus Priest.As for Jades, i think they're fine. They just gave Druid too much stuff.
Maybe Jade Idol to 2 mana? Hall of Fame the Auctioneer?
Also, I'd find it hilarious if Jade Idol is moved to 2 mana and negating the purpose of Geist.
One thing about the Druid Jade cards are that Jades are valued at 2 mana for neutrals, but only one mana for class cards. The Druid cards are the most powerful with a 1 mana summon a big dude (or 1 mana 1/1 which you can start the game playing) and a ramp card, especially good with the card draw at 10 mana. Hitting Jade Idol or Jade Blossom would do a lot to make Jade Druid less powerful, although overall it seems fine.
Playrate of Jade Druid is pretty down; I very rarely get mirror matches anymore. It feels like I queue into a lot of Tempo Rogue and Zoo Warlock (although VS Reaper has Jade Druid as the 2nd most popular deck at 10% of the decks played). Win rate wise, Jade Druid is the worst of the three meta Druid decks (Big Druid, Aggro Druid, and Jade Druid).
So, no, Jade Druid isn't a problem and in 6 months it'll rotate and Wild has much stronger decks.
