There should be a queue meant for new players that they can't really select to be out of.
Not like forcing them into player vs AI but having separate queue's between people who are experienced/seasoned players and people who are just picking up this game like me. I've recently gotten into games where players have mentioned smurfing for new accounts to get into (high rank) for the new season. and I'm a person who barely knows how to play many roles and I don't really own many champions to play said roles with. It doesn't seem really fair at all to play games against people who are super skilled when I barely understand whats going on outside what guides I have seen told me to do.

hit you with their stun they'll be able to burst you down if you're playing a squishy champ.
