So lets talk ranked

I love this game to heart and I've put a lot into it but ranked is a joke I'm in bronze cuz its my first ever season and i cannot win for my life for example i just got demoted to bronze 4 in the last game before i did it was such a joke. I played maokai top got 3 kills early and when my team started losing lane i would tp to help i pushed mid i pushed top a ton and had a little under 200 farm by 20 min i built a lot of defensive items and played careful only dying twice after i had picked up a few more kills i wasn't raging or saying anything bad about my team feeding but just trying to keep moral up saying things like come on guys we can win this lets just group and would help team fight some more well pushing top but we lost and this pissed me off a ton ranked is a joke in bronze and is the luck of the draw i played to the best of my ability and yes you could tell me well you don't win em all but from what I've seen you win none i play like this most games and yes ill admit i do have a bad game sometimes but the many other games i play like this and do everything i can possible do to help out but theres always someone who feed and i try and help but it doesn't matter i lose ever game anyone feel this way and could you help me out with what i should do to win some cuz the only way i see is queuing up with my gold 2 friend but whats the fun in winning a game when your just getting carried
