Players new to pvp, please stop buying green wards more than once per game.

Upgraded stealth totem becomes available at level 9 for 250 gold and the sightstone is available throughout the entire game for 800 gold. These are both vastly superior to green wards and give much more value throughout the game. Pink wards are good buys because upgraded vision trinkets do not function in the same way that stealth totems do (1 stealth at a time, infinite duration unless destroyed vs 3 at a time, limited duration) and upgraded vision totems are crap for this reason. Constantly buying green wards keeps you further away from buying a sightstone or more productive items. Once is okay if you are forced to back without the money for a sightstone or before level 9, but no more.

You may think this is uncommon, but look deep into what items were purchased at what times in your match history if you are not playing ranked or are low elo. You'd be surprised how many supports buy 3+ green totems, even when they have enough money for sightstone or upgraded trinket at level 9. I thought it would be better to enlighten the few people who do this than to just assume it's not a big issue.
