Also going full AP soraka - is it me or does she still not do a huge amount of damage? Shes quickly becoming my fav support over Leona (never thought id see the day), but her damage is questionable (basically Leona does no damage and whilst shes a good tank I'm finding at my elo theres just a need for the support to be a damage dealer aswell)
Support should always be poking or disuading the opponents ad from last hits but as a damage dealer i'm not so sure. Soraka with her silence is quite potent for that though and she can keep feeding the ad carry with mana as well.
Sona is probably my favourite, just because her Q chord in particular does a nice amount of damage on the 3rd Q. But her chords in general I just find useful. Soraka's heal is insane but unlike taric or sona she only does a single heal and the cooldown isn't great
