People bitch about Lucioball, but its the one OW game mode where you can carry two idiots.
Tips on winning at Lucioball:
-Don't crowd the goal: Let the goalie protect the goal. A second or a third person does nothing but fuck things up.
-Zoning: Keep the ball on your opponent's half of the arena.
-Self-Control: Don't hit the ball just because you can. If you're going to hit it somewhere non-productive, or take away a good shot from a teammate, just leave it alone.
-Patience: Aim the fucking ball. You don't always have time to line up great shots, but you get more opportunities than you may realize.
-Mechanics: Learn the mechanics of the game mode (the boop-punch combo is a lifesaver). You'd be surprised how many people don't know how to boop the fucking ball, let alone more complex mechanics.
