LF a serious Duo partner/5's Team

Hello im look for a serious Duo partner and or 5's team. My highest rank has been silver 2 or silver 1 ( i cant remember). Im currently bronze 3 due to a lack of playing and trying new things. I started out as a support main but I have been playing everything trying to get better. I'm not looking for people who rage or blame other people. I would pref playing with people who are better than me so i can learn but anyone who is serious and wants to get better is ok. I work 3rds so i generally play from 3-8 PM CST.
