Sometimes when I had to support I played Soraka. Many think Soraka isn't very strong.Well she isn't but she still works fine in bronze atleast. The interesting thing though I did when playing Soraka was buying Spirit of the Elder Lizard for the lols. It was so much fun. Rushing Spirit Stone and philosopher's stone followed by Boots then double Long Sword. Now of course the lack of Sightstone forced me to buy sight ward every time I based. Once I had Spirit of the Elder Lizard Sightstone was next. From there it was a normal support build. I played so aggressive that the bronze Thresh ran away from me.
I know this is just not very viable but in bronze is it fun. Plus this makes Soraka look playable again.
