A practice mode would be nice

Please add a practice game mode where you can try champions, even the ones you don't own.

I understand that you can try champions in a bot game. But this is why I prefer a practice mode: 1-You can try champions you don't own, which certainly helps new playes who wanna try a champion before buying it. Instead of having to wait for weeks or even months till that champion goes in the free rotation.

2-You should have infinite gold in this mode. So you don't have to farm for long time just because you want to try a certain build.

3-You can control your champion's current level.

So I really wish this was a thing so I can practice champions before I buy them. Besides most other Moba games have a practice mode.
