As you all know, Soraka recently received a gameplay update with new abilities with some similarities to her old abilities. What have her ability changes pushed her towards, mid lane or support?
Telling what is the best role is a kind of difficult question. However her Kit is mainly built around supporting right now. She has More CC than before and also a higher healing rate (at the cost of her own HP). Soraka is even stronger in team fights than before simply because of her increased range on Q. Also her Ultimate got buffed a lot for more healing on targets below 50% HP. The AOE, Silence/Root also really boosts her team fighting potential.
So basically: You should play her as a full AP supporter. She will still be sort of viable in the mid lane, however her top viability is rather questionable since her potential lay in being an unstoppable pushing force top and she kind of lost her pushing power with her Q getting more Cooldown.
