% of warding support is responsible for?
This is obviously a noob question, but I just played my first provisional game and it occurred to me. I main support, and once I get my Sightstone/related item I drop wards wherever seems reasonable until the end of the game. On the couple of occasions the game has gone long and I've had thousands of gold (so I could theoretically grab a stronger item), I keep the Sightstone item (Eye of the Watchers in my case) because warding is part of my job. I think that's correct, though I love my AP on Sona and will gladly take an excuse to get more.
I had a game earlier where someone kept complaining we had no vision. He was correct, but I was doing what I could to keep things warded. We either had very few other wards or the other team did very well clearing them, I'm not sure which. Thus my question is, is there some kind of consensus on how many people (or which roles) should keep the initial warding item and which ones (if any) should switch to a sweeper? At lower elos, should teams lean one way or the other? I would think lower rank players should go more for wards than sweepers because you're more likely to play against people who either forget to ward or won't sweep for yours, but I've only played about a dozen games since returning and that's nothing more than a guess.
