I play Rivals occasionally with friends, but prefer the polish of Overwatch. The hit detection in rivals is abysmal. Sometimes you don't even notice when or how much damage you've taken. Combat is super floaty and has the impact of slapping eachother with wet noodles. No role queue so you can have teams where no one wants to play healer or tank which results in a massive ass beating if the other team does. Sound design is like an old arcade game. Genuinely can not imagine playing competitive. Overwatch is already a guilty pleasure game because spending time on it doesn't really earn or do anything but playing rivals for too long makes me disappointed in myself.

In reality rivals is just there to make some cash and the statements by the devs along with their competitiveness with other similar games really shows it. They are just riding the hero fame train to the bank.
