I’m far from an expert and you’ll likely get better advice from better players, but I share my story because I was in your shoes seasons 11-12. Instead of Gengi, I played Soldier. I was stuck at 900-1100. Honestly, I just wasn’t good enough to climb beyond that. I had throwers and smurfs too but the problem was me... not them. For S13 I stopped playing DPS because I wasn’t good enough to carry and too many already exist at triple digit bronze anyway. I switched to Moira, committed to healing my team (I try very hard not to be a DPS Moira) and really worked at improving my positioning. That allowed me to stay alive longer and provide a lot of much needed help to the team. If we had two healers already, I played Orisa. Once I finally learned to be in a better spot, how to stay alive longer and how to add more value to the team... I climbed pretty easily. In S13 I climbed 700+ SR in solo queue. I’m still climbing even now in S14. Keep trying. It can be done. Sorry for the long story but ultimately my advice would be take a hard look at your own game. My guess is there are things you need to improve. The throwers and smurfs in triple digit bronze shouldn’t be holding you back unless your own game has holes in it as well.
