soraka bugged going mid lane

done so 3 times now and after the game it doesn't give me a rating at all, even when i win lane and our team wins the game, fought a talon mid lane and wrecked him using E silence to keep him from comboing when he jumped on me and then Q to just self heal like 75% of the damage was ever doing to me, and last game i just played was vs a lulu who was able to out poke since soraka Q has longer range that most of her ability's and when ever she tried coming in close i placed my E, so i have been doing very well as soraka mid ap build but after game it doesn't giving me a rating.
