I've been playing quest druid with jades in Wild all night, that quest is absolutely ridiculous.
The passive hero power is so strong I often get too many jade golems in my deck and I feel forced to run more and more card draw every time I play the deck. I' ve got 2 UI and 1 Overflow, I'm think of adding auctioneers.
Even in standard I struggle a lot more against quest druid than rogue. The rogue reward is a weapon hero power that you can't even use entirely every turn and it does only one thing, 3 damage. It's linear, predictable and slow, this quest is totally fine. I would be more worried about quest mage/druid
Top quests in standard are druid > mage > shaman in my opinion
