If you have skype, know fluent English, you are keen to learn, and you are not offensive, then I am willing to impart my wisdom.
I typically like going over your replay and pausing a lot, so you learn a lot from your own gameplay. I will also give you lessons I have learned myself, since these lessons will be valuable to you as well.
Further, I will talk about in-depth things about solo queue in particular, so you can get really good.
Tell me your username and I will teach you whenever I have free time :)
