Billed month to month.
When I started playing ranked I was in Silver 5, but I always felt like I could do better. I started to figure out what I was doing wrong by asking questions to ProGuides' top ranked staff (Genius) and watching their advanced guides. I climbed all the way through Silver and Gold. I'm now in Platinum division and still climbing.
I had been stuck at rank 8 for a bunch of seasons in a row, even when I had the best decks in the meta. When I signed up for Proguides I realized what I was doing wrong and I learned how to master the best meta decks to finally get to Legend.
I began playing League for the first time at the beginning of the year. I started using ProGuides before I even reached level 30. The knowledge I gained from these guides dramatically improved my gameplay. Once I reached level 30, I jumped right into ranked games. Having nearly a decade of experience in other MOBAs such as Dota, I have never used a site like this, but I'm so glad I did. I learned fast enough to reach Diamond in less than 4 months.
