Duo for ranked (Bronze)

I usually play around 7-10PM so I don't know if I can join but I definitely want to get out of Bronze. I play everything except supp, not saying I am unwilling just not very good with supp items. Am Bronze 5 with a current win rate of 61%, I play passively early game, focusing on farming and catching the enemy out of position. I play more aggressive towards late game but my main focus is always objectives and not kills. I've seen games where my team has the most kills yet no one likes to push lanes so we end up losing.
