My brother doesn't play often, only like 2 ladder games each day and maybe a couple more on weekends but he got his 100 wins in 1v1 quite quickly and am already promoted from Silver to Bronze in a short time. I play less 1v1 and more team games and my learning is much slower compared to my brother who just mainly play 1v1, so all in all more laddering in 1v1 is a must if want to improve quicker.
