1. What makes a class more suited toward control then others?
The classes that are best for control have access to a tool kit of cards that enable them to stall the game, survive and run their opponents out of resources. These include healing/armor, board clears, Taunt Minions and single target threat removal. Sometimes these can be found outside of a classes own tool kit, like good taunt minions, but in some metas they cant be.
2. What makes warrior such a great control class?
Powerfull AOE effect (Brawl), Armor as a survival mechanic, good/flexible removal options (Shield Slam, Execute)
3. Why doesn’t control hunter work?
Poor AOE, traps can be played around, No healing, some of their control tools like Explosive trap, freezing trap, and the kill a random minion card are wonky at times. Hero power doesn't help survivability or controlling of the board.
4. What classes do you think will be suited for control going into the new year?
Priest and Warrior look like the best control classes. It's been so long since this game didn't have instant lose match ups for traditional control match ups that I will have to see how things like Academic Espionage Rogue hash out to see if it will even work again.
