Support = Buy Sightstone
It's kinda ridiculous how many Bronze playes don't know to rush a sightstone early game. I just finished carrying a game where i had to buy 7 greens and 1 pink (it nv got found; by the river) because the braum support didn't think it 'necessary'. If i remember correctly he said something like "I dont need it if i dont keep going into enemy jungle" (yes he must have been either <10 yo or have some mental issues because what he said made no f;ing sense to me). After upgrading his lane item, getting Sunfire cape, he got a BoRK (WTF!?). I mean he did alright the whole game, it coulda been worse and he coulda been a feeder or something, but seriously what a way to play. All early to mid game the gragas jungle kept roaming and getting kills, usually from mid whom i told to buy wards and of course he never did. Seeing this was the reason i told braum to rush a sightstone like 15-20 mins in but he didnt listen either. If i wouldnt have bought so many wards i'm sure the lack of vision woulda made things much more difficult and coulda possibly lost us the game. Seriously, if you play support and don't buy wards, don't play in ranked at the very least.
EDIT: Oh and after the match he said "you don't need sighstone if you not getting ganked". Dude.. If yo uread this and think the same, the whole point of sighstone is to avoid a gank. Make it so that the jungler wastes his time trying to get something to happen... Dont wait till the enemy adc gets that double kill on ya and then take ay tower for you to decide you need sightstone.
