Apprentice Mode
In all honesty the levelling from 1-30 is a joke. I am levelling a smurf and new players get treated like dirt. I have seen a lot of games where a player says he is in the right to curse out another teammate if they are doing bad and one even said he doesn't have time to explain to them a mobafire guide. I think there should be a game mode where you can join somebody in a game and give feedback easily watching their game where you could queue up with somebody and it would only be the only lane you queue'd up for with ganks at random intervals. You could make people want to do it with a rating system if they feel they were helpful and give out summoner icons for it.
I know this might not be viable but something needs to be done to where we can help new players learn the game better than feeling like they should just afk or that everybody in the player base does this. I haven't seen it as much on my main but it seems a lot of the smurfs don't care if they treat somebody else like trash and have a personality of a 10 year old. Something should be done in all honesty because reporting somebody on an account they don't really even care about doesn't seem to help.
