Riot needs more educational videos

So dumb finding players who still don't know the basics of team building and play, once example I found today is when my team and I aced the enemy team they all just randomly started to recall and dragon and baron were free and if I had not pinged and typed DRAGON FREE BARON they would of just went to base like WTF is wrong with players.

Another example is in champion select some players just either dont understant how to properly build or just dont give a fuck, but you can't realy say they don't give a fuck because they are easly to rage when they are losing but not stop and think that maybe we needed a tank support and not a brand.

Another example is the infamus split pushing, players don't seem to understand that split pushing is a legit strategy and just rage at you for not grouping, while they fight the enemy 4v5.

Some simple aspects of the game are being forgotten when a few seasons back they were well known, maybe because all the players are now high elo and Im just sitting at gold 5 even when Ive been playing since season 2.
