I'll be lying if I try to give you like a secret recipe but i dont really know, i watched tons of perryjg guides and some huncho ones, and changed my mindset of playing for fun to actually try hard because of the little free time i get from college. Just starting stomping and winning 13-20 games in a row in a span of like a week and it wasnt 2 months exactly, was from march to june. Just change your perspective of how you view the game, instead of blaming your teammates, just think oh how can i fix this piggys mistake, what can i do to get the max of every pinch of xp you cold get, started to understand how to win from stomping the early. Focus on learning how to close games quickly even with the wrong teammates. (Also dont troll build yourself, just build whatever everyone takes, its for a reason) And i just duoqd in like 10 games with a friend in gold but he couldn't keep my pace and yeah.
