Well, considering you've only played in S4, that means your rank MMR was non-existent. This means in your 10 ranked games, you had Silver 1 to Gold 1 players to start with. To end up in Bronze, you have to lose a minimum of about five games. My rank was silver at the end of S3 and half way through S4, I was plat 1. RL kept me away for about three months though, so I dropped to 5. I'm now back in Plat 4. I've also been in Bronze. At the start of S3, I was Bronze because of the League system kinda screwing up everything. ELO after 10/10 wins was about 1200-1300, depending on what ELO your enemies were, which was considered Bronze still, so... League system introduction didn't make us re-do the first 10. They shoved us into ranks based on ELO. Despite this, I went from Bronze 4 to Silver 1 by the end of S3 and into Plat 1 in S4. If I can do it, anyone can 'cause I know I'm not a pro. You play your best and stay quiet. Mute your teammates if you have to. Trust me. Been there, done that.
