This video shows complexity vs nip at katowice. You get to hear complexity and all their glory while in teamspeak. You hear how they interact, what types of calls they make, plus you get to see how they aren't as complex (see what I did there) as people make them out to be. They have roles and their roles are based on what basic strat is called. Its more than just that though. Just watch and pay attention to how they talk over each other but are able to pick out the info that is needed.
