The point isn't that control is so shit that it litterally cannot win against aggo, the point is that control needs to draw into it's defensive cards early or they just flat out lose to the hyper aggression. There isn't really an hierarchy in HS where it theoretically be:
Control>Aggro, Aggro>Combo, Combo>Control
That just isn't the case, aggro right now is so heavily favored because 90% of their decks are centered around super powerful 1-3 drops which they constantly machine gun out throughout the game.
