I have spent the past three years playing competitively in games such as TF2, LoL and OW, almost exclusively from a main caller position. During that time, I've gathered a relatively deep (compared to the time I've invested) understanding of both the technical and communicative aspects of getting up to 5 other nerds on the same page in the span of a solo q game. If you ever wanted to improve your main calling, both generally and/ or specifically, talk to me here, on Steam, Battle.net or through League (message me for handle).
