Silver is a little better, I was able to get out of Silver 5 pretty easily! Playing jungle and sticking to one champ when I can definitely helped. Rhaast is really good at carrying because he can deal with tanks which people in my ELO aren't great at. I also tried to focus on not dying and whenever my team got a kill or took an objective I try to say something like "gj!" or "nice work".
Next stop, gold!
