I've been grinding elo myself. Gone from 1300-1500 in 2 days. It sucks, every game I always get fed, but my team is either retarded, afks, or just feeds because they're bad. But in the end I always end up carrying usually, not to be cocky or anything, once in a while my team will be decent and actually get fedish up to my level and we just compete for kills in the end. Happened to me earlier today.
