Soraka is 1-0-27 in two weeks of LCS play
0-0-14 last time TiP picked her, 1-0-13 today.
On one hand, this is a small sample size. On the other, it's like the shoutcasters were saying, Soraka is a very safe lane and a very safe champ who can just stand back and heal up the ADC. Thanks to her, TiP only gave up 4-5 kills across an entire match.
At what point do we need to ask if an AFK healer is great for the game?
Yes she's very gankable. However, that kind of requires you to depend on your jungler to gank and for him to be someone who can contribute to a fight. That doesn't always happen. As TiP vs C9 showed, you don't always get a good gank that works and when you do get something, Shen comes in and saves the ADC by blocking an arrow with his face.
Edit for game 2: she just went 0-3-20, so she finally died. Still in 3 games she's 1-3-47. Still too safe IMO.
or any other support with a lot of cc for that matter.
