Learning these 3 mehanics makes no sense
1 last hiting - as zed for example is preety much easy to last hit. u don't have to worry about freezing because u can't get ganked. he is only 1 example. if u can't last hit as talon- just uninstall, don't even play it anymore unless u're not level 30 yet. 2 kiting - if you're adc main and wanna learn how to kite, just don't bother yourself with that and play kalista or ashe. 3 wave control - PUSH, play cho/zed/talon ETC and fucking push. use brain and wards. on bot lane freeze if you're ahead and last hiting should be easy because you're AD and your support will zone enemies for you.
just play 10-15 games every day, waste your life and there you go, you just learned LoL.
