I have been playing LoL, more or less regularly, during 5 years (since Xin's release)
I main mid in soloQ : Ahri & Cassiopeia. Else I try to play botlane. I used to play Zyra, Twisted Fate, Katarina, Leblanc (before she became popular and banned).
I Achieved Platinum in season 2, 3 & 4. Not ranked in S1.
I just got promoted Diamond, in 270 games and 57% winrate, starting from a Gold V account due to inactivity and bad placement games at the beginning of S5.
No experience in team yet.
