Needs to be a better matchmaking for Onslaught! Nothing but trolls trying to do 6 missions!!!!

Riot is treating Odyssey like normal Solo q / Blind pick when it's not. 90% of my games on Onslaught (and i've played like 100 at least) have ended in surrender before it even begins or just troll afk's because some one's got 1 augment or all augments.... or some one needs all sona but everyone wants all yas cuz they haven't got the first part of the mission done yet so they think all sona is troll even tho it's an actual mission. There needs to be a real LFG for this or more options when Queuing up! Not just are you going to get lucking 1 out of 20 times? This is honestly one of the most troll game types i've ever played on any game ever and i've played in D5 NA.
