I, like most Conq mains, play him for his superior block. Alot of people hate the superior block, but removing it would alienate already existing Conq mains. Leave that alone and you keep Conq's existing base.
He can feint too. I attack into Full Guard Stance, then attack from another direction, guard break, shield bash, or even zone attack if they're low enough to give up that much stamina.
His attacks get a good amount of forward movement so its tough for opponents to create any space if they're exhausted.
He's taken a bit of a hit, but he's still a fair character.
