Fall of the support? Bottom lane synergy

In norms in solo queue I've noticed 3 things that have been abysmally terrible lately.

1. In my games, 1-2 out of every 10 supports get sightstone/vision or even think it's their job to do. Worse it's been in years imo. I think this has to do with the rise in non-traditional supports lately. (I.E. Nidalee support responds "Nidalee isn't a support" when asked why no sightstone, yeah but you queued as support soooo)
2. ADCs not letting their supports use Relic Shield charges. There is a blue charge literally floating around Leona in plain sight and she furiously swinging away at the large minion..... and Jinx waaaaits for it... and last shots. "Jinx! Let me kill large ones please" "okay" 1 minute later last shots "JINX!" "oops". Rinse and repeat. It can be confusing when the support swings at everything (supports please don't swing at everything, timing man.) but when the support literally only attacks when there is a charge present, that attack should be a clear indicator to the ADC not to attack that minion. There is literally NO benefit to the ADC and in fact it hurts them. You lose the tiny bit of HP and your support falls behind in farm. Underfunded support means weaker bottom lane which is bad for ADC. I have to mention my charges I would say.. 2 out of every 3 times I play with a random ADC and of those times I mention it I would say less than half of the time does the ADC completely correct their behavior.
3. Supports going off alone to push lanes etc. Stay with the ADC but if not stay with SOMEONE. Leona can roam and gank but don't go and try to push top alone?! The support will say "I'm not dying!" or "I just cleared that wave!" Yes but top or mid couldve cleared that wave 2-3 times as fast and your stun/slow/hook would've been really useful in that last fight. Just because you CAN do it, doesn't mean its the BEST USE of your skills.

I just feel like supports themselves and the rest of the team aren't taking the role of support seriously since the last few patches. Traditional support skills like hooks, slows, and stuns etc. aren't being picked as much, vision isn't being used and the "buddy system" for supports isn't coming it to play. You're not going to carry as a support, but that doesn't mean you can't win or lose the game for your team.
