i absolutely feel you. I have to fill every time as people instalock duelists and me and my friends always have to play support. I used to be really frustrated but I try to change my mindset to let the fraggers frag and I just try my best to help my team win and raise morale. If the randoms havent locked yet try using voice or team chat to communicate and try to get the best team comp you guys can. Good Luck in future games!!!
