Expanded training
So, I thought about how cool a real training would be especially for new players. You got that training section where you can learn on any map anything. There's a training for kiting, last hitting, smiting (baron and drake stealing) etc. For laning, every player can once or twice try every champion, after using those chances up you can only play the champions you own and those that are in the free rotation. The laning training is adjusted to which champion you play and to the lane you want to play the champion. So you could play Poppy Jungle or Poppy toplane and have two different trainings.
You can choose things such as champion, lane, main focus etc like you choose the settings for custom games.
That's my idea, I hope you like it.
