I was Silver 4 last season, went 3/7 in my provisionals and got knocked down to Bronze 5. I made it back to silver in 120 games playing mostly Diana mid, Volibear top and Jungle, not really much ADC and Leona support. Leona is more or less my main because not many people are willing to support and Leona is super strong. So yes, I made it from Bronze 5 to Silver 5 maining support, it is possible people. I am now in Silver 3 and climbing happily. Just stay positive, don't give up, don't flame, and play multiple roles well (Fiora/Riven/Yi/Kat instalockers I'm looking at you) Everyone can get better and go from the depths of bronze to mid/high silver relatively fast if they do it right and are confident in their own skill. I plan on getting to Gold and leaving bronze far behind.
