Marvel Rivals has taken over the hero shooter genre, partly because it lets you play as and fight other Marvel characters, but also due to fans of the genre not being satisfied with the state of Overwatch. The superhero shooter not only represents beloved characters well, but the devs have also ensured that their powers lend well to gameplay.
I've never played Overwatch, so I didn't endlessly compare it to Rivals during the beta.
Marvel Rivals is not without fault, though. Much like Blizzard's shooter, the lack of role locks has resulted in the formation of team metas where certain roles are completely left out. However, there also seems to be an issue with the third-person perspective that affects aim accuracy in the game.
If you've ever taken the time to study the aim accuracy of Marvel Rivals, you'll know that aiming a bit to the left of enemies results in a missed shot. While that sounds completely normal, it seems aiming a bit to the right of them results in a direct hit. This also applies to melee attacks. This isn't because the crosshairs are placed wrong, but due to a known issue with third-person perspective games....
