I used to have this problem. My friends would be holding me back from playing the way I wanted to play. I'm not saying you should leave them, but I found new friends who I play with all the time when were online. 900 ELO though. Damn. I once played with someone from "down there". Got a win on the first game and he was ecstatic. Got the armour piece and he couldn't believe what was going on. Think from their position. Their crucible reality is to be beaten by those better than them. So to them, you are someone who can win. That's why they "latch" onto you. When my friends ask me to play with them, though we aren't going flawless, I am having fun and getting passage coins.
