You did well with Kayle. However, that said, don't give up on Soraka. Youre still learning her, and she is a very powerful support. If played correctly, she and the AD Carry can dominate bot with little resistance. It is very hard to push that combo out of lane. If you want to try and learn another team support like Janna is, try Sona. I haven't seen you play her yet. I find her to be very fun and useful to the whole team. And she can stun a whole team which is super effective in team fights. She also has a slow with her power chords. I think her CC is in line with Janna's, though the support with the most CC is Alistar. You should definitely try him too.
