So, I've been playing for a month or two and thanks to my brother and friend's tips and lots of playing, i think I'm doing pretty well. I got an S on Karthus once, but haven't been able to since. Soraka and Karthus are my two mains so far, but the best I've been able to get since that time was an A+... and that's including a poro king game with 16/10/22 and 21/6/22. I was sure for the second i would have gotten one, but no, just A+.
even with Soraka, B+ is the best i can achieve it seems. (I do admit, I'm not the best soraka, but I'd like to think I'm decent)
So... Anyone have tips for getting an S rank?
