Fist Timing A Champ In Ranked

Now Im not talking about using a champ that you know how to play in a ranked game for the 1st time. I'm talking about these people who for the very 1st time ever playing the champ decide they want to learn the champ in a ranked game.

I know there are some few occasions where someone might 1st time a champ they have never played before in a ranked game and have a good game. But from my experience over the past couple years the large majority of the people that do this, that is not the case. And they end up playing a large role in the team not winning.

I think at the least it should be considered assisting enemy team because I do not see how doing this is the best thing to do to help your own team.

People could easily just not let it be known that they have never played the champ before so I think there should be a system in place where the game will not even let you pick a champion that you do not have a certain amount of games played with for ranked. Even if its just 5 games.......enough to have some clue of what your champ does. So that you don't end up sitting at the fountain forever wondering what to buy or sitting under your tower trying to read how each of your abilities work.

Or so that it does not prevent people from being able to trade champs during champ selection it could be set up where a player can pick the champ so that they can trade it a teammate. But if they do not before game starts then that player is kicked as if he dodged and everyone just goes back into que.

Just want to get others opinion on this.
