Tutorial Modes

I think it would be interesting if Riot were able to implement a Tutorial Mode where you could pick a specific area that needed improvement and the game would modify to make it easier for you to do that. Like you'd be the only human in the game, the rest would be bots, and you could actively work on that specific aspect that needed work. I feel there are big hole with "Bot games" as training tools, and learning in PvP mode is really stressful for me, as getting flamed for mistakes is a surefire way to send me on tilt. Last hitting and "jungling" as a whole are things I need work on desperately, but the experience for jungling is not the same in a bot game (no counter jungle) and last hitting or practicing my rotations on champs is tough when tryhards in bot games racking up high KDAs for fun come into your lane and "help". Plus, people do use bot games for practicing jungle anyway, and I hate trying to learn a top champ and failing miserably everytime because I don't know enough about the champion to know how to get strong enough to 2v.
