Supports

So i having a conversation with a couple of friends the other day about how i felt that its kinda weird that most supports can just deal out decent damage. I look at sona for example as one of those supports that once shes done with her support items and is doing fine can build into AP items. Once she builds into those ap items can deal massive damage. But then i look at or and im left thinking what about them ? I mean soraka got that rework but her damage with her q kinda falls off early . I was then told by my friend that riot wanted soraka to be a complete support but that just sounds weird to me. When i was told that i was like o_0 what about the other supports lol. So i felt like expressing that and hearing other peoples thoughts.

P.S I actually really enjoy soraka just dont enjoy not being help other then W and E and ult then that is all. Her Q feels pointless once its mid~late game(other then you getting hp back from others).
