Hail, climbing the ladder has shaped my mindset in good favor, what applies in game can apply to any other hobby/life mission/goal.
Malzahar(mid)is my champion of choice to swiftly climb. However in lower elos, he scales too slowly in this snowball meta. To compensate for this I am currently practicing with a few other hard carry champs so that I have options when it comes to boosting in mid.
I am proficient in Top, Mid, Adc, and Support.
In Iron through Silver even as far as Gold I prefer top lane. It's volatile, and I can capitalize on enemy mistakes easily for a hard carry.
