From my experience in Silver (A LONG fucking time compared to most), it was hell. New accounts are easier to rank up because of elo. Without any game sense, I was trash. The worst. I got placed S1. Took me months to get out of silver. By the time I actually committed to it, my elo was so shit that it took forever to rank up. To get from S3-GN1 I had to win about 30 games in a row. At this point I had so many games played, that it took me THAT long. Now, I have bought a smurf and when I try, I can rank up almost every game. Now of course I have about 1k hours dedicated to the competitive aspects and about 600 to bhopping, but elo definitely effects it. Now I'm DMG, so if you think this is biased, think again.
