Some of these I feel are overdue especially for Warrior and Druid. I'm not saying all of these nerfs need to happen but I would be happy with any combination of these
Raid the Docks final stage of quest requires 3 pirates
Defias Canoneer change to 2/2 3 mana or 3/3 4 mana
Mr. Smite Your Pirates have Rush
Wildheart Guff costs 6 mana up from 5
Kazakusan At the Start of the Game: if you have at least 5 dragons in your deck, Battlecry: craft a custom deck of treasures (I know this nerf is very unlikely because they don't usually change cards this drastically)
Seafloor Gateway costs 4 mana instead of 3
Azsharan Mooncatcher / Sunken Mooncatcher make sunken mooncatcher summon another sunken mooncatcher and not a copy. This prevents Lightforged Cariel from being able to drop two heavily buffed minions for the price of one. Hearthstone has had a history of changing cards to operate this way.
Switcheroo costs 4 mana up from 3
Twin-fin Fin Twin summon another Twin-fin instead of a copy. Same reasoning as the paladin card.
Such a dumb ideas
