Random support player: But, they don't provide me stats that contribute to my champion!
Me:
Need I say more?
/salt
as a support main
i never have enough wards, my sightstone runs out to fast, control ward only lasts in 1 spot, and i have to take sweeper most games because my allies dont know how to cleear wards or place them half the time ...
and even when we see the incoming enemy and i back off, my team ignores their minimaps and the ward warning and just dies then blaims me ...

PSA: Your support having a sightstone is not an excuse to not use your trinket.
Other then that I must say, the three sightstone build up items are pretty bad...
Remember folks: Wards Win Games
This is true, though if I have 0 charges left of my sightstone and you have 2 charges left of your trinket, it might be a good time to make use of them instead of running into the blindspots in the jungle, die and then proceed to yell "we need vision" to me.
Error 404: item not found - twisted treeline-
Me:
You don't play support too much, do you? First back, if I have the gold, I'm always going to buy Forbidden Idol. Piss on the Sightstone, we have 4 wards from botlane alone (2 + 2), which doesn't even include jungler (+2 more since he'll usually ward common spots for a Sightstone Ward).
Not only that, but all 3 of those items are worthless. The only thing you get from either of those 3 is the extra slot, which almost never comes into effect anymore. (Games usually end in 25-30 minutes, supports are 6-slotted at 40+ with their lack of money, assuming they went only cheapo items.) If the meta were a bit slower to favor slots and late-game, then sure, those 3 would be good for conserving a slot. But you know what to do late game instead? SELL SIGHTSTONE! That 6th slot could be a useful item instead ( 
to give your ADC the 50% Crit their lacking or 
if you're a tank), not just +150 HP and Wards that really aren't gonna do much since your team is probably gonna be 2 Oracles and 3 Farsights.
Supplementary PSA: Building SS right after gold item is rarely the best choice. Support usually buys it after team phase begins or after they complete their core item(s). And everybody on a team needs to ward, unless something is actively stopping you from doing so (such as you being unable to even recall without losing a turret). That means buying a 
as soon as it's viable (read: Your inventory isn't full of 800+g items, and you have at least 75g) and pressing 4 on a random bush now and then.
The support is the primary person to provide vision, but the entire team needs to contribute to it. The support is limited to 4 wards at a time. You are limited to approximately 3 at a time. Together, the entire team has up to 16 wards, discounting blue trinket. 16 is superior to 4 in every way, so don't cut your team's vision by 75% because of laziness.
######Yes. Even Jhin thinks 16 is better than 4. 16 is four 4's combined. Four 4s is better than one 4.
And people wonder why nobody wants to cooperate as support. Listen to yourself, you asinine nuisance-- you just demanded an entire wing of players play to your specifications, because you want them to do things specifically for you.
Nobody likes support and nobody plays it cooperatively because it always gets treated like total shit. Support mains are fucking tired of watching their carry lose and getting blamed for it. Well damn son, I guess I'll just ward against that goddamn skillshot you walked into??
If you perceive a weakness in your team's warding, fix it your damn self. Pinning it on another player is just saying, "I can't do it so someone should do it for me." You're welcome to say that, but I guarantee your response is going to be unpleasant. Of course it is-- look at your goddamn attitude. Yes, sir, I guess we're all here to make your plays look good.
You are why premades exist.
You play a team game, you ward. Period.
It's interesting how the other four people not warding is just as much as a problem as the support not buying sightstone, yet I see fifty of these goddamn threads and not much for the other four people. Yes, not buying sightstone is a detriment to the team, but so is not contributing to vision at all.
Honestly, I'd rather the support rely on their trinket than have any other person on the team not use their trinket at all. It should be a team effort, yet everyone is focused on the support because it's easier to tell if someone has a sightstone than if they're warding or not.
Let's take your last ranked game that ended up in a defeat.
http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2495376218/209737627?tab=overview
Vayne ADC.
Didn't switch to blue trinket for range and safety.
An average of .25 wards a minute (or one ward every four minutes).
Your support handled 48% of the entire team's warding, and everyone on your team had the default green trinkets.
Not a single sweepers.
Not a single seer stone.
And it's not like the other team did so hot either, but the irony is that their support didn't buy sightstone unlike yours who did, but their team's warding is nearly 20/20/20/20/20.
Here you are, making a PSA about how supports should buy sightstone when you're incapable of doing your part of the vision game. Maybe learn how to use blue trinket and actually ward before you tell others how to do it, okay?

Don't rush 
on ANY CHAMPION, especailly vayne unless you are trying to lose

Might want to learn item build orders before ranting about other people. If I was supporting you, I'd be raging.
On Vayne try 
start with

Then go into either 
or if you want
Static right now is incredibily strong and cheap. Good wave clear and it's damage to champions was buffed.
If you don't want to do that, at least do

You can ward across the map, but that won't stop them from diving you. Rather get something with combat stats.
