I have no idea what this means. But awesome! Sounds good!
In League of Legends there are 5 tiers with 5 divisions in each and one tier with one division. bronze>silver>gold>plat>diamond>challenger. To go from silver 3 to silver 2 you need to win a best of 3 and to go from silver 1 to gold 5 you need to win a best of 5. I won a best of 5 without dropping a game and I just found out it was my 8th ranked win in a row.
Last I checked Gold (the rank I just got) is the top 25% of the community on NA.
