1. The hit boxes in Concord are unbelievably generous. If your cursor is anywhere close to the opponent, you're hitting them. This was a conscious design choice.
2. Concord provides players with a number of low skill floor heroes. Lark, Daw, Jabali, Emari, and Kyps can be played relatively effectively by players who can't aim.
3. The game doesn't punish teams for losing. You rank up and unlock cosmetics at exactly the same rate whether you win or lose. This means high skill players don't feel held back by their low skill teammates to the same degree.
4. The game leans heavily on Rock, Paper, Scissors design philosophy. That means low skill scissors players can beat high skill paper players when they bump into them in a 1v1.
