People know nothing about gamemodes

I've noticed alot of people don't know how to play certain gamemodes such as nemisis, which was this weekend. For instance, i was just in a game where everyone except me and my buddy didn't know how to play. So imy suggestion is that each gamemode has a tutorial mode, where players are introduced to the old draft pick, (since some leaders don't know that they're banning) and where they get the feel for what's different in this gamemode, both in champ select and on the rift. Some gamemodes don't need this though, like hexakill and urf, where the gameplay is affected in such a way that doesn't need a tutorial. But the number of noobs I've encountered this weekend who banned op champs and gave op champs, and ruined the game before it even started. Another minor solution would be to implement dynamic queue into blind draft games, so that newer players (who haven't seen the old draft pick) are in a familiar environment.
