PLEASE. Add some Real "How to Play" Tips to Teach Players

This is half rant, but completely serious.

I'm sick of having: Teammates getting ganked by the enemy team repeatedly.. and STILL be holding onto 2 trinket wards.

Teammates that gank then feel they deserve bonus cs, ignore any and all warning pings, then die an unnecessary death to the enemy.

Teammates that, for some inexplicable reason, believe they are carrying the team while being 6/6/0 and can't understand why others are losing their lanes.. to the enemies he/she fed.

Teammates that demand the Support buy a Sighstone and get wards on the map while they haven't placed a SINGLE NO-DURATION-LIMIT CONTROL WARD. Let alone buy one.

Teammates that all jump forward to fight the "killable" enemies while the fed one(s) kill our carries uncontested, then dps the rest to death.

Teammates that ping to attack or ping on-the-way, then run the other fucking way, leaving anyone that followed up on the ping to fend for themselves.

Teammates that run away from a "fight" while we have a visible numbers advantage and a single tank already took the brunt of multiple ultimates.

... I could go on, but I think all of these seem pretty basic, no? I'm at most Gold / Silver, but isn't it strange that so many players lack the basic fundamentals of playing this game?

I think it's past time that tips, at least from Pros or something, be put out for normal players to learn from, without going out of their way to find it.

Seriously, players shouldn't be so damn oblivious about how this game ought to be played outside of "hit them and try not to get hit".
