I am a 3.2k mmr player, this year I went from 500 mmr to 3.2k in 2 months just by analyzing my games and watching my replays. While I might be new to Dota, I think the ranks I have gained prove that I am still improving! You can just not pay and get the coaching for free, but if you think I did a good job, even a $1 is good enough as payment. I love to help others!
