Non tank supports and their role in the current meta game.

So this post is mostly to ask other peoples thoughts on where non tank supports stand in the game. This does not include non traditional "supports" (ziggs, ekko, Rengar, basically any other traditional mage/assassin being used as a support).

As it stands i really enjoy playing Sona, but i often feel like i don't really do anything for a large part of the game. Since i'm support i can't farm, (you know because sona is so well know for ability to do that /laugh), and unless my team goes for a bunch of early ganks and i get a ton of assists, i don't usually end up with enough money to start building something beyond the standard support items need (boots, sightstone, mana regen + cooldown reduction item) until i'm somewhere around level 12-14.

While i can't say for sure, i think i would likely experience a very similar issue with almost all the other non-tank supports. I know the couple times i've played someone like Soraka or Nami i've felt like i wasn't doing all the much unless the enemies were very stupid and just stood in all my abilities.
