Jungle Soraka on the same level as jungle Jarvan, Pantheon and Olaf? And better than Volibear and Fiddle?

Who has ever jungled soraka? oO

I had and it rocks

well if you know about stonewall008 you'd realise that this isnt a list to be used for team composition, it just takes into account the speed, sustainability, versatility and gankability of the hero NOT the viability. And it happens to be that soraka clears the jungle very fast with sustain, and decent gank due to silence and red buff applying to it, if you look at his youtube video explanation about soraka, he says it "not that its ever gonna happen, but its possible"
