I played league of legends at season 1 for the first two months of the game, i had a level 28 account, however due to the lack of professional players at the time, i decided to quit. Dota 1 was much better for me.
Well were you playing just ranked or mostly normals? Did you dedicate any time in learning the game better? Trying new champions, New roles AKA lanes or playing with friends? I was stuck in bronze- Low Silver for 2 years that's because i was too stubborn to try anything else.
