Control just has too many tools now.
Back in the day there were only a few aoes or power cards to worry about. Pala had Tirion. Warrior had Brawls. Mage might have 2 Flamestrike. It varied, but you could swing a game if you pressured enough to force those cards early, baited them with false threats or knew when to hold or play your answer to them (like you had a Hex and knew Tirion might be in their deck, knowing when to save it or use it was vital).
Nowadays control warrior doesn’t care about wasting a Brawl or Warpath on smaller threats. They still have 1 more of each, 2 Dyna, Zilliax, Booms hero power, Rush on every mech to use as removal, 2 Shield Slam, 2 Omega and so on. It’s basically impossible to bait removal in Hearthstone. You put down one or two small threats to be safe and they’ll walk all over you with minions, armor up and never run out of health or removal. Commit to the board, they wipe it in one card and you lose.
Playing smart and having knowledge of the game just doesn’t help. It used to be “oh control, I’d better save X card for their X card, bait out X removal, aim to build this board to avoid that card”. Now it’s “oh control, 78% chance I lose. I’ll go all out agro and hope they don’t draw board wipe X by turn 5”.
