Back in the day was when? When I played rated games multiple times per week in 2012-13, I also played on that resolution and without mouse and was ~1600-1700. I did not think that a top player would lose so much just because of a mouse.Laptop with 1366 x 768 res. Had it for a long time and just stuck with it. I hookup a mouse of course, no keyboard though (tried playing on the touchpad for fun and was hard fighting 1600s back in the day 11).
