i thought it was kind of funny, but reffs would do the arm-band pulling motion and then remember that there were no armbands. They would come tug on our jerseys where armbands would normally have been.
I think they need arm bands to officially clarify if a player is out. There were many times when the ref who point at you but u were never sure if u were out. One player on our team the ref called our so he stood up checked himself did see a hit on his arm so he then kneeled back down and the ref was like u just called urself out so get out. And my teammate was like well you pointed and called me out when i wasnt. So yea i think its better to have armbands to officially clarify calls. Although i thought the reffing could be way better.
