As for Janna specifically, most people do not know how strong her Zephyr is when maxed early, as it completely nullifies most bruisers, especially those without a gap closer (such as Udyr, Shyvanna, Nasus, Volibear). She also counters assassins who require burst to get kills, such as Xin, Talon, and Panth, as her Eye of the Storm is very strong. However against bruiser who have reliable gap closers/CC(or CC reduction), such as Jax, Lee, Mundo, Darius, she is food, and will be ruined.
PS: Soraka is very bad, and is considered a troll pick. You get a handful of MR and now her Q does nothing for damage, as her team quickly loses their 2v3 teamfights.
