Odyssey onslaught is a joke
So ive been trying to play Odyssey on onslaught and its literally impossible. I think ive queued up for it around 15 times and only about 3 of the times i ended up getting with teammates that tried to kill Kayn. In 80% of games there is at least 1 player afk or just trolling because they didnt make everyone pick 2 augments. And i have never ended up in a game where everyone comes along and picks 2 augments. So naturally i havent even been able to complete onslaught difficulty once. My suggestion is that you add some sort of filter where players that want to play with 2 augments, get with others that want 2 etc.
skin
After that i never won again because everybody wanted 2 augments instead of 3
Riot should have considered filters for the event,as it doesn't exist
My advice to you is create a premade team,if you can't find enough friends search from discord or something,at least that will solve the augment and afk/troll problem but the rest its up to you friend
