Wut?
Soraka is fun?
You must be drunk. She is probably one of the most boring champions in the game.
I hate "This champ is boring" arguments. It's all relative to the person playing. For example, I find Soraka to be just as fun as playing someone like Thresh.
For me, the core of the fun is doing my job in the role that I've chosen. As a support, that means paying attention to the map and disrupting the enemy, while providing opportunities for my ADC.
Soraka's simpler kit allows me to focus more on the map, and even pushes towards that aspect a little bit with her Wish being a global effect. The sustain provided from her allows your lane to slowly get ahead with repeated small skirmishes and her silence gives you a large window of opportunity to harass freely.
edit: I guess Soraka is boring because she makes the lane too easy.
