Riot shields are corny
The site that I play at allows people to use them whenever they want, and theyre super OP. Even when I completely outplay them, they still win most of the time.
Having a piece of plexiglass that youre allowed to blindfire past is corny and makes the game less fun for your opponents. I get that there are some scenario type game types that they could be used in but the tiny lightweight ones that are easy to carry and maneuver with are dumb.
