Can we get some videos that show advanced but mandatory elements of the game?

Probably just QQ but as a Silver V, there is at least a solid 30-40% of players in Bronze to Low gold who don't understand how vital last hitting / farming is, warding as a support and picking appropriate champions (appropriate as in not countering yourself, not if a champion is meta) and its just makes low elo more infuriating than it already is losing not because both teams were equal in knowledge and one made overall better plays, but that your ADC has no farm and that your mid laner thought he would play Lux against a Yasuo.
