I DONT LIKE TO LOSE!!!!

I started playing computer games at an early age and dowry was among the first games. The first time I started with dota1 I most often played the position pos1 and pos2 but after I switched to Dota 2 I chose to play support / hard support. I am 27 years old, I spend a lot of time on the computer in dota2 and I came to the idea that I want to return to a team. I don't like the idea of playing ranked with random players because I don't know how to play the position I choose. I speak medium English and I know how to be part of a team more than that I am also very positive. Also, my favourite hero is Dark Willow
